If you want to develop a program on Arduino with Raspberry Pi, then this tutorial has all the steps you need to take for it, in detail.

While a Raspberry Pi is a full-fledged computer that can do more complex things than an Arduino microcontroller, it's not the best choice for every project.

Of course, Arduino has been available on the Raspberry Pi for a very long time with sudo apt-get install arduino, but this was an older version that cannot work with newer Arduino boards.

The Ultimate Arduino Coding Power Course Bundle can put you well on your way to a coding and programming career with 59 hours of courses covering Raspberry Pi, Arduino, ROS1, and ROS2.

TL;DR: As of April 4, you can sign up for the All-in-One Raspberry Pi and Arduino Developer Bundle for just $69.99 — that's less than $8 per course.

To get started, you will need to install the Arduino IDE and add the Raspberry Pi Pico board to the list of supported devices.
