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 any variables or start any libraries. The loop() function runs continuously after setup() and is used to execute the main logic of the program.
