Hello everyone, in this article we will show you Program Arduino on Raspberry Pi. Arduino and Raspberry Pi are two very different products, but both are aimed at avid hackers and hobbyists. What if we could connect an Arduino to a Raspberry Pi and use it as a slave device: a device that responds to input and sends output to our Raspberry Pi via Python? After all, while the Arduino isn’t a full-fledged computer, there are some things it can do better, like analog-to-digital conversion with its built-in ADC chip.

There are two categories when wiring code for your Raspberry Pi Pico. An easy way for new users is to use a version of Python such as Micro Python or Circuit Python. A more advanced method is to write the code in C/C++, which is aimed at more experienced users. There is now a third way to write code for our Raspberry Pi Pico, and that is through the Arduino IDE, which uses the “Arduino language”, a derivative of C++. Since Arduino has been around for many years, there are many existing “sketches” (Arduino’s term for programs) and tutorials. If you’ve worked with Arduino boards before, you may already be familiar with this powerful IDE and language.

We want Raspberry Pi to be used by kids all over the world to learn to code and understand how computers work. The main Pi had a solitary processor clocked at 700MHz and just 256MB of RAM, and the latest model has a quad-core CPU clocked at more than 1.5GHz and 4GB of RAM. Raspberry Pis generally cost under $100 (usually around $35), especially the Pi Zero, which is only $5. Running a program on an Arduino is simple, but have you tried the Pi? Raspberry Pi is powerful enough to be a standalone PC and powerful enough to program a microcontroller. In this article we will talk about programming Arduino on Raspberry Pi.

How to program Arduino with Raspberry Pi

Installing the Arduino IDE

Step 1: Open Microsoft Edge Chromium and go to And if you don’t have this web browser, you need to download Microsoft Edge Chromium

Step 2: Select “Linux ARM 32 bit”.

Step 3: This should bring you to a page that allows you to download and/or donate. If you don’t want to contribute, you can click “DOWNLOAD JUST”.

Step 4: This should open a new window. You can change the file name at the top and the download location on the left. The “Save” button is in the lower right corner.

Step 5: Once the download is complete, you’ll find it in your Downloads folder (or whatever folder you choose). Double-click it to launch Archiver. It may take a few minutes to open.

Step 6: Archiver will open your file, but it will take a while to read it. In the bottom left is a circle that flashes red and green. Wait for it to finish before doing anything else. At this point you can take a glass of water.

Step 7: Click “Extract files”. That’s the open brown box with the orange arrow pointing right.

Step 8: A new window will open allowing you to select some settings. You can change the value of the top text box to point to the “Downloads” folder. Otherwise, it should point to the “tmp” folder by default. Click “Extract” on the bottom right to complete the download.

Step 9: Close Archiver, navigate to the new folder and double-click the “install.sh” file.

Step 10: Click “Execute” in the new window.

Step 11: The Arduino IDE should be available in “Pi logo -> Electronics -> Arduino IDE.”

Step 12: Arduino IDE installation is complete.

Programming with the Arduino IDE

Step 1: Launch the Arduino IDE from the Pi logo. A green window will appear where you can write your code.

Step 2: Copy and paste the following code:

void setup() {

// put setup code here to run once:

Serial.begin(9600);

pinMode(LED_BUILTIN, OUTPUT);

}

void loop() {

// put your main code here to run repeatedly:

digitalWrite(LED_BUILTIN, HIGH);

delay(500);

Serial.println(“LED is on”);

digitalWrite(LED_BUILTIN, LOW);

delay(500);

Serial.println(“LED is off”);

}

Step 3: The code causes the LED to light up and print “LED on” on the serial monitor for 0.5 seconds, then does the opposite, turning the LED off and printing “LED off” for the same amount of time.

Step 4: To save, click “File -> Save” or press Ctrl + S on your keyboard.

Step 5: Connect the cables. The Arduino Uno uses a USB Type-A to USB Type-B connector. The square side goes to the Arduino while the rectangular side goes to the Raspberry Pi.

Step 6: To upload to Arduino, click “Sketch -> Upload” or press Ctrl + U on your keyboard.

Step 7: After uploading, the TX and RX LEDs will flash rapidly, and then you run a program that makes the L LED light up or off every 0.5 seconds.

Step 8: To make it a little easier to see, you can try connecting an LED bulb and a 250Ω resistor between D13 and GND. Do this on a breadboard to make it easier and make sure you disconnect the Arduino from the Raspberry Pi before doing anything with the pins.

Step 9: If you did it right, the LED bulb should light up and dim at regular 0.5 second intervals.

Step 10: To access the Serial Monitor, click “Tools -> Serial Monitor” or press Ctrl + Shift + M on your keyboard.

Arduino label

After that you should be able to do anything with the Raspberry Pi and Arduino. If you want to go back a bit, on the off chance that you do this a lot, you’ll need to check out the article on making things better with Arduino. Always remember the expression: off, code up, off.

Pins Off

How about we take each of the wires to pins. In case you take the time for another task, chances are you didn’t proactively remember the points you were assigned. For example, you can wire the result nail to “HIGH” along with one other result nail to “LOW”. That’s one easy way to break a GPIO nail on a microcontroller chip!

Code up

Code up is basic: upload your code. Always remember that the Arduino is constantly being controlled when it is connected to the USB port.

Turn off

Finally, while you’re rebuilding your circuits, consistently power off by removing the Arduino from all power sources. The last thing you should do is put some unacceptable wire in some unacceptable place at that extremely horrible second to have smoke pop out of whatever you’re doing. Keep in mind that short circuits can destroy your task instantly.

Final words

We hope this article on how to program Arduino with Raspberry Pi will help you and solve all your problems. Any board, as long as it is supported by the Arduino IDE, would work with the Raspberry Pi. It’s basically the equivalent of programming on a regular PC with a Linux spread. The ability to program the Arduino should work with all Raspberry Pi chip sheets except the Zero, which does not have its own USB ports. This also does not apply to the Nano, which cannot run the Raspberry Pi OS. Besides programming, there are other things to do with the Raspberry Pi. Apart from Raspberry Pi, you can also install Arduino IDE on Ubuntu.
