Circuit Documentation

Summary

This circuit integrates an Arduino Nano microcontroller with an analog joystick and a fan motor (L9110). The joystick provides two-dimensional input to the Arduino, which then controls the operation of the fan motor based on the joystick's position. The Arduino Nano is responsible for reading the analog signals from the joystick and driving the fan motor through its digital pins.
