5MM Red Diffuse LED

– The LED (Light Emitting Diode) is an important component for your project that needs a light source or some signaling effect. It is made up of a semiconductor material, which emits light when a voltage is applied to its terminals. The LED has polarity, that is, it must be connected correctly with the anode (larger terminal) connected to the positive, and the cathode (smaller terminal) connected to the negative.

Specifications:

– Color: Red;
– Diameter: 5mm;
– Operating voltage: 1.9V~2.1V;
– Operating current: 20mA;
– Brightness: 300 MCD.

Code for arduino:

#define LED 13  // The pin the LED is connected to
void setup() {
  pinMode(LED, OUTPUT); // Declare the LED as an output
}

void loop() {
  digitalWrite(LED, HIGH); // Turn the LED on
}
