User Button
The XRP Controller Board includes a "USER Button" which we can use to control our robot.
Find the USER button on your XRP --->
Note there are 2 other buttons on the Pico board:
The "BOOT" button is used to update the firmware.
The "RESET" stops the running program and resets the Python interpretor.The USER button is connected to pin 22 on the Pico, which is also wired to the "Extra" connector.
