Step 1) Install Arduino IDE
Visit https://www.arduino.cc/en/software and install the latest Arduino IDE software for your computer
Step 2) Install Arduino Mbed OS RP2040 board to support Pico:
Open Arduino IDE ->Tools ->Board Manager
In search bar, search pico , you will find a board name “Arduino Mbed OS RP2040 board “, Click Install button to install the latest version for this board into IDE.
Step 3) Install RP2040_PWM library
Download the RP2040_PWM.zip file from https://osoyoo.com/download/RP2040_PWM.zip
Then Open Arduino IDE-> click Sketch->Include Library->Add .Zip Library->upload the RP2040_PWM.zip file to IDE
Step 4)Download and Run the Arduino Code:
Please download the code file from https://osoyoo.com/driver/pico_car/lesson1/picocar-lesson1.zip
Unzip the file and run the picocar-lesson1.ino sketch file through Arduino IDE, after you upload the code, please put the car to ground, turn on the power and your car will move forward, backward, left turn and right turn.
