IR Emitter Brick

Product Description

This is a brick component specially design for the Arduino board, used to transmit a certain signal in the infrared spectrum. You can use this to control any infrared remote controlled device, like TV, air conditioner and such.

It connects with just two wires to Arduino ( GND for power, and IN for the input signal).

The GND pin on the brick should be connected to the GND pin on the Arduino board, and the IN pin on the brick should be connected to a digital pin on the Arduino board (do avoid digital pins “0” and “1”, those are used for programming purposes).

After connecting it to the Arduino board you can drive this kit just like a normal LED. Although the LED won’t be visible to your naked eye, you can use a video camera, cell phone camera, or digital camera to see if the LED is working properly.

The source code is below:

void setup() 
{                
 pinMode(7, OUTPUT);     
}

void loop()
{
 digitalWrite(7, HIGH);   // set the LED on
 delay(1000);              // wait for a second
 digitalWrite(7, LOW);    // set the LED off
 delay(1000);              // wait for a second
}
