Lesson 57: Calibrating a Joystick in MicroPython

This tutorial covers calibrating a joystick with the Raspberry Pi Pico W:

• Wiring Setup: Connect ground to pin 38, 3.3V to pin 36, VRX to GPIO pin 27, and VRY to GPIO pin 26.

• Code Implementation: Import machine, time, math; set up ADC for joystick axes; read and print joystick values.

• Calibration: Convert raw ADC values to a scale of -100 to +100, adjusting for neutral position noise.

• Homework Assignment: Write a program to calculate and report the angle of the joystick based on its position.
