Code Documentation

Arduino GIGA R1 WIFI 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 GIGA R1 WIFI. The setup() function is where you initialize your settings, and the loop() function is where you place the code that you want to run continuously.
