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 called once when the program starts and is used to initialize variables, pin modes, start using libraries, etc. The loop function runs continuously after the setup function has completed. This is where the main logic of the program is implemented.
