Code Documentation

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. Currently, both functions are empty and can be filled with the specific logic required for the circuit's operation.
