The picoRoboticCar is a project that involves building and programming a robotic car using a Raspberry Pi Pico. This project aims to provide a hands-on experience with Raspberry Pi Pico. I have not use this microcontroller and like that you can use C/C++ or a version of python called MicroPython.
For this project I have decided to implement as much as possible from scratch using C and C++.
- Robotic Car Kit, this is the one I purchased SunFounder Robot Car Kit
- It includes everything you need for the car
- Rasberry Pi Debug Probe
- Visual Studio Code
- Install Rasberry Pi Pico extension
- I discovered this extension will do the full installation of the toolchain
