Documented Code

Arduino UNO R4 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 UNO R4 WiFi. The setup() function is where you initialize your components, and the loop() function is where you place the main code that runs repeatedly.
