SunFounder ESP32 Starter Kit
In order to communicate a full range of motion to the computer, a joystick needs to measure the stick’s position on two
axes - the X-axis (left to right) and the Y-axis (up and down). Just as in basic geometry, the X-Y coordinates pinpoint
the stick’s position exactly.
To determine the location of the stick, the joystick control system simply monitors the position of each shaft. The
conventional analog joystick design does this with two potentiometers, or variable resistors.
The joystick also has a digital input that is actuated when the joystick is pressed down.
