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 where you initialize your components and settings, and the loop() function is where you place the main code that runs repeatedly.
