RED LED

Grove - Red LED houses an LED light source. It has a potentiometer to control the brightness. 

Interface: Digital

• Step 1. Connect Grove-Red LED to port D2 of Grove-Base Shield.
• Step 2. Connect Grove Shield to computer.
• Step 3. Copy the below code to Arduino IDE
• Step 4. Upload the code to the Board

void setup() {
  // initialise digital pin2  as an output.
  pinMode(2, OUTPUT);
}
 
// the loop function runs over and over again forever
void loop() {
  digitalWrite(2, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(2, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

4-digit display
