Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, a KY-023 Dual Axis Joystick Module, and a 16x2 I2C LCD. The Arduino UNO serves as the central controller, interfacing with the joystick for input and the LCD for output. The joystick provides analog input for two axes and a digital input for a button press, while the LCD displays information via the I2C protocol.

Documented Code

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino UNO. The setup() function is where you initialize your components and settings, and the loop() function is where you place the main logic that runs repeatedly.
