The benefit of that, though, is - because Arduino is multi-platform - ArduBlock works on Windows, Mac, or Linux. Plus, having Arduino already present makes the transition from visual programming to text programming easier, when the inevitability approaches. Installing ArduBlock can be a little tricky - there's no installer, just a Java file. Open terminal and type: ls /dev/tty. Note the port number listed for /dev/ttyUSB. or /dev/ttyACM.The port number is represented with. here. Use the listed port.

Arduino is awesome! It's our go-to electronics education platform, and it's our top choice for rapid prototyping, but it isn't for everyone. Maybe it's the cryptic language, or the Java-based IDE, or maybe it's just the teal window border -- regardless of your reasoning, if you're trying to escape the Arduino IDE, here are a few alternatives we'd like to share.
The Arduino alternatives covered in this tutorial range from simple, introductory graphical programming to web-based Arduino interfaces for your web browser. Here's a quick overview of each interface covered, we'll go into further detail later on:
ArduBlock -- A Visual Programming Arduino Extension
ArduBlock is a graphical programming add-on to the default Arduino IDE. Instead of memorizing cryptic functions, forgetting semicolons, and debugging code, ArduBlock allows you to build your Arduino program by dragging and dropping interlocking blocks.
ArduBlock is a perfect interface if you're just getting into programming, electronics, or Arduino. Check out the ArduBlock section of this tutorial for an introduction and quick getting started guide.
Minibloq -- Visual Programming Standalone Software
In the same vein as ArduBlock, Minibloq is a graphical programming environment where groups of blocks are stacked on top of each other to create your program. Unlike ArduBlock, however, Minibloq is a stand-alone program -- no Arduino install required.
One of Minibloq's most powerful features is its real-time code generation -- as you drag blocks into your program, the equivalent code is generated concurrently. This makes Minibloq an excellent tool for beginners to intermediate programmers.
Check out the Minibloq section of this tutorial for an introduction to the interface.
..and Beyond
Those are the alternatives we'll be discussing in this tutorial, but there are many others worth checking out, including:
- Scratch for Arduino -- More visual programming! Scratch for Arduino (S4A) is a riff on the popular Scratch programming environment. If you're an experienced Scratch user, this is most definitely worth checking out!
- Modkit -- After a successful Kickstarter campaign, Modkit is well on it's way to producing another great visual alternative to Arduino. Check out their website and get a feel for their browser-based visual environment.
- Arduino IDE for Atmel Studio -- Atmel Studio is an incredibly powerful tool for programming and debugging AVR chips like those on the Arduino. If you're looking for a more advanced approach to Arduino, or Atmel chips in general, check out this extension to Atmel Studio.
This extension can be an extremely powerful tool -- complete with breakpoint implementation and a host of features you may be used to from more advanced IDE's.
ArduBlock
ArduBlock is a programming environment designed to make 'physical computing with Arduino as easy as drag-and-drop.' Instead of writing code, worrying about syntax, and (mis)placing semicolons, ArduBlock allows you to visually program with an snapped-together list of code blocks.
ArduBlock builds on the simplicity of Arduino, and creates a perfect beginner gateway to physical computing. Instead of tearing your hair out debugging, you can spend your time creating!
Installing ArduBlock
ArduBlock is something of an 'add-on' to Arduino, so it requires that you have the Arduino IDE installed. The benefit of that, though, is -- because Arduino is multi-platform -- ArduBlock works on Windows, Mac, or Linux. Plus, having Arduino already present makes the transition from visual programming to text programming easier, when the inevitability approaches.
Installing ArduBlock can be a little tricky -- there's no installer, just a Java file that needs to be stored in a very specific location. Follow the steps below to install it:
- Download and Install Arduino (if you haven't already) -- Ardublock is an extension of the default Arduino IDE, so you'll need to have Arduino installed on your computer to run it. Check out our Installing Arduino IDE tutorial for help with that.
- Download ArduBlock -- Click the link to the left, or head over to the ArduBlock Sourceforge page to find the latest and greatest version.
- Identify your Arduino Sketchbook location -- This is a folder on your computer where your sketches and libraries are saved by default. To find your sketchbook location, run Arduino, and open Preferences by going to File > Preferences. The contents of the top text box defines your sketchbook location. Memorize that location and close Arduino.
- Create [sketchbook]/tools/ArduBlockTool/tool/ -- The Ardublock file you downloaded earlier needs to live in a very specific location within your Arduino sketchbook. Navigate to your sketchbook, then create a nest of three directories: tools >ArduBlockTool >tool (watch out, each folder is case sensitive).
- Paste 'ardublock-xxxxxxxx.jar' Into /tool/ -- Paste the Ardublock file you downloaded -- a JAR (Java ARchive) file -- into the last folder in the nest you created.
- Start Arduino -- Or restart it if it was open.
- Select the Board and Serial Port -- Just as you would if you were using Arduino, make your board and serial port selections from the 'Tools' menu.
- Open ArduBlock -- Run ArduBlock by clicking Tools >ArduBlock. If you don't see an entry for ArduBlock here, double-check to make sure your directories are all correctly typed and cased.
ArduBlock works hand-in-hand with the Arduino IDE -- it relies on the IDE being open in the background, so don't close the Arduino window!
Using ArduBlock
The ArduBlock window is split into two halves. On the left there are 'bins', which store every possible block you can add to your sketch. The blank, gray slate to the right of that is where you 'draw' your sketch. To add a block to your sketch, simply drag it from the bin into the blank, gray area.
To begin, every ArduBlock sketch requires a Program block, which you can find in the 'Control' bin. The Program block defines the setup
and loop
functions that every Arduino program requires.
From there, you can drag more Blocks over, snapping them into either the loop
or setup
sections. Here, try making a blink program. The set digital pin blocks, which effect a digital output (analogous to Arduino's digitalWrite
function), are found under the 'Pins' bin. The delay milliseconds block, found under 'Control', is analogous to a delay
Arduino function.
Then click Upload to Arduino to send your drawing off to your Arduino board. You can ALT+TAB back over to the Arduino window to check your code upload status.
After you've successfully uploaded your first sketch, continue to play around and explore the contents of the other bins!
ArduBlock Tips & Tricks
You can clone blocks, or groups of blocks, by right clicking and selecting 'Clone'. Everything from the block you right-clicked to the bottom of that 'group' will be copied and pasted into the top-left corner of the window. This is a huge timesaver for bigger drawings.
You can temporarily remove code from your sketch by dragging it out of the entirety of the 'Program' block. Anything not connected to the main Program block will be ignored when your code is compiled. This is a great debugging tool -- you can remove a block of code from program execution, while not actually deleting it, much like commenting out code.
Finally, if you peek back over at the Arduino window, after you've uploaded an ArduBlock drawing, you may notice something different. To create your code, the ArduBlock program simply parses your blocks and spits the equivalent Arduino code over into the Arduino window.
This becomes a great learning tool if you're interested in transitioning from graphical programming to text.

DEV-12651Minibloq
Minibloq is a visually-driven programming environment for Arduino and other physical computing devices. Instead of tearing your hair out over syntax, variable types, compilation errors, and the other annoyances of code, Minibloq allows you to construct your program using a series of graphic blocks.
Beyond the gentle, visual introduction to programming, one of Minibloq's coolest features is its real-time code generator. As you add blocks to the Minibloq drawing, an equivalent line of code will be generated in the next window over. This is an excellent tool if you're looking to make the leap from graphic programming languages to text.
Minibloq has a major focus on robotics. It includes support for popular robotics platforms, like Multiplo and our RedBot Kit.
Getting Started with Minibloq
Head over to the Minibloq download page to grab the latest version. Be aware that, for now at least, Minibloq is (mostly) only Windows compatible.
By default the interface is split into three columns -- hardware view, Minibloq editor, and code editor. On the main toolbar up top, you can choose which columns you want to display or hide.
The hardware section allows you to pick your Arduino-compatible board among options including RedBoard, Arduino Uno, Arduino Leonardo, RedBot Kit, and others.
The middle, Minibloq editor window is where you'll spend most of your program-building time. This view works hand-in-hand with the detatched 'Actions' window, where you click buttons to add blocks to your program.
Finally, there's the 'Generated code' view on the right, which is the most powerful learning feature of Minibloq. It's a huge aide in easing the transition from visual programming to 'coding' programing.
Creating a Minibloq drawing takes some time to get used to. Try creating a blink program to get a feel for it:
Then check out some of the included examples by going to File >Examples. Among the many example sketches are a collection of SparkFun Inventor's Kit and RedBot Kit specific programs. Check 'em out!

How do you program an Arduino using a Mac? This blog will tell how. But before we get into that, let's take a look at what is an Arduino?
What is Arduino?
An Arduino is basically a single board microcontroller that is used for building digital devices and interactive objects that can sense and control objects in the physical and digital world. These Arduino boards are available both in preassembled form or as do-it-yourself (DIY) kits. Arduino board designs use a variety of microprocessors and controllers. The boards come fitted with sets of digital and analog input/output (I/O) pins that can be interfaced to several expansion boards or breadboards (shields) and other circuits.
One of the biggest advantages that Arduino boards have over Raspberry Pi is the fact that they can read sensitive values from sensors and Arduino boards have analog input and output and not digital input output which is the case with Raspberry Pi. This is why in some instances - especially where exact values are needed - it is a more apt choice. Say, if you want to make a device that automatically waters your plants. Now to do this, you have to measure the exact soil moisture, so an Arduino is a better bet because it can read analog values as opposed to the Raspberry Pi which will need another chip to read analog values.
Arduino has low maintenance and doesn't get disrupted by power outages. But image processing needs can be done better with Raspberry Pi and Pi camera.
In this blog, we shall look at how we can program an Arduino board using a Mac OS. Here's the step-by-step process to program an Arduino board with a Mac:
Downloading and installing Arduino on a Mac
Step 1: Get all the needed equipment in place. This means having with you the Arduino Uno board and the USB data cable that will help you connect the board to your Mac.
You'll also need a breadboard, jumper cables(M-M), an LED and a resistor (with a resistance of say, 330 Ohms).
Apple mac os for pc. The Apple mouse makes it easy to navigate with smooth scrolling, and the Magic mouse features a multitouch surface with gesture support. You can add extra storage for your MacBook, transfer large files between work and home, or back up important data with a Mac external hard drive. Explore the world of Mac. Check out MacBook Pro, iMac Pro, MacBook Air, iMac and more. Visit the Apple site to learn, buy and get support. Explore the world of Mac. Check out MacBook Pro, iMac Pro, MacBook Air, iMac, and more. Visit the Apple site to learn, buy, and get support. Global Nav Open Menu Global Nav Close Menu; Apple; Shopping Bag +. Apple doesn't want you to install macOS on a PC, but that doesn't mean it can't be done. Numerous tools will help you create an installer that will allow to install any version of macOS from Snow.
Step 2: Then start by connecting the narrow end of the USB data cable to your Arduino board as shown below.
Step 3: Then connect the other end of the USB data cable to your Mac. At this stage, your Mac and the Arduino board have been connected to each other using the USB cable. Refer to the pic below.
Step 4: Now go on to download the Arduino IDE on your Mac. To do this, open Safari on your Mac and just go to the website www.arduino.cc. Once you have opened the website, go to the software section and click on downloads from the dropdown menu. Now select the Mac OS X version, hit download and wait for the download to finish. Once it downloads, one can run the Installer in the next step.
Step 5: To install the IDE, we need to run the file that we just downloaded. Click on Agree and continue with the default settings for the rest of the installation. Once the installation is done, click on the close button to finish the installation.
Now that we have downloaded and installed the Arduino IDE on our Mac, we can carry out a number of tasks using the Arduino IDE. This includes getting the board to say, 'Hello World', running the counter program and lighting an LED - all using the Arduino.
Saying 'Hello World'
Arduino For Mac Catalina
Let's look at what goes into writing our first program, the 'Hello World' program. Let's open the Arduino IDE that we have installed on the Mac. Make sure you check the board name under the Tools option as Arduino Uno. Also make sure that the communication port is selected as COM3. Now to see the information sent by our Arduino, we have to open the serial monitor we see on the right.
In the program, we start by putting Serial.begin 9600 in the void setup function which is the one-time setup required for exchanging information over the serial port from the Arduino to the computer. 9600 here is called the baud rate. It is the rate at which the Arduino can send symbols or characters to the computer.
In the void loop function, we use a very simple serial.print to show data on the serial monitor.
You can first save it and then upload the design onto the Arduino. You'll then see that the words 'Hello World!' are being sent by the Arduino to the computer and we can see the words on the serial monitor. You'll see that the words 'Hello' and 'World' are appearing next to each other. However, if we use a n in our print command, we will see the two words printed one below the other.
Running the Counter Program
Let's take a look at the next program. We will design a simple counter by opening the Arduino IDE and the serial monitor. Let's start by defining the counter variable. Here we say int counter equals one and add a semicolon at the end. This initializes the value of the counter to 1 at the beginning. Now just like in the previous program, we initialize the serial connection.
In the loop, we print the counter value and we also increase the value of the count by one. Here, we use the printIn function to automatically add a new line after having printed the value of the counter. Now this would be too fast and for us to understand what's happening in the output, we add a delay and the argument is in milliseconds. So for a one second delay, we provide an argument of thousand to the delay function. Finally, increase the value of counter by one using the counter++ statement. Once we save and upload this design onto the Arduino, we will be able to see that a counter variable is constantly being increased in value and this value is being communicated to the computer over the serial connection.
Lighting an LED
Lighting the inbuilt LED on the Arduino
Now the next program we will be working on is blinking the Arduino's inbuilt LED. You can see that right next to pin number 13 among the digital pins, there's an LED which is orange in colour. We will learn how to make it blink once every second. And just like we do with the Raspberry Pi, we will start by initializing the pin to be an output so we can control its values. Here we say pinMode and we say 13 which is the pin for the inbuilt LED and we set it as an output so that we can send values of high or low. We then begin our loop function by setting value of the 13 pin to 1 (or high). We do this by using the DigitalWrite function. We then add a delay of one second and then we set the value of the 13 pin as low. Don't forget to add a delay after turning it low. Now when you run the code, you should be able to see the light next to the pin number 13 blink.
Writing the program to blink an LED on the breadboard
Here we will see how one can write the program that allows the Arduino to make an LED on the breadboard blink once every one second. Just like in the previous case, we will set values and this time, we will choose pin number 12 and we will set it as an output. So we type the pinMode, 12, output. In the void loop, we use the serial to communicate messages from the Arduino to the computer. We use the DigitalWrite function to turn the pin on or set it to high. Then we add the delay of one second. In the same fashion, we will turn the pin off by using the DigitalWrite function. Similarly, we can add a message and a delay so that we see the output very clearly.
Next you can save and upload this. Go to your Arduino, make sure you have the serial monitor open so you can see the output. Now this code seems to work as it prints LED high and LED low every one second. At this stage, we need to make an LED circuit on the breadboard and connect it to the Arduino to see the actual result.

Making connections to blink an LED on the breadboard
Now we will explore the connections to be made on the breadboard so as to make an LED blink from the Arduino.
Here's how you make connections to blink an LED on the breadboard using an Arduino:
Just like with Raspberry Pi, we set up the LED first. We place the LED on the breadboard across the middle separation.
Then we add a resistor (say with a resistance in the range of 220 to 600 ohms). We place one end of the resistor on the same line as the LED.
Now we connect the resistor's other end to the railing for the Ground.
We use a wire to connect it to the Ground pin on the Arduino.
The closeup of the Arduino after the connections have been made will look like this.
We then connect the other end of the LED to the pin number 12 which we are programming for.
The closeup of the breadboard after the connections have been made will look like this.

Since the program is already on the Arduino, we should immediately be able to see the light blink.
