Circuit Documentation

Summary

This circuit is designed to control a CNC machine using a combination of stepper motors, a joystick module, and an Arduino UNO microcontroller. The CNC Shield V3 is used to interface the stepper motors and joystick with the Arduino. The circuit also includes an LED with a current-limiting resistor and a power supply to provide the necessary voltage.

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 used to initialize any settings or configurations, and the loop function contains the main code that runs repeatedly.
