Documented Code
Arduino Nano Code (sketch.ino)
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
This code serves as a template for the Arduino Nano. The setup() function is called once when the microcontroller is powered on or reset. It is typically used to initialize variables, pin modes, start using libraries, etc. The loop() function is called repeatedly and contains the main logic of the code. It is where the microcontroller will spend most of its time.
