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.

However, the Arduino can achieve several things that a Raspberry Pi can't. Arduino and Raspberry Pi models are both affordable, and there are many Raspberry Pi projects that won't break the bank.

Programming the Raspberry Pi Pico with Arduino IDE The tutorial on Hackster.io provides a comprehensive guide on how to program the Raspberry Pi Pico using the Arduino IDE.

GPIO programming on a Raspberry Pi using Arduino's Web IDE - this post brings Raspberry Pi and Arduino together.

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.

The Raspberry Pi team has released the Pico, a $4 microcontroller that competes with Arduino.

Despite their similar appearances, Arduino and Raspberry Pi are two different classes of devices. Arduino is a microcontroller board, whereas Raspberry Pi is a single-board computer.
