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, and the loop function runs continuously after the setup is complete. Currently, the code does not perform any specific actions.
