Grove - Infrared Receiver
The Infrared Receiver is used to receive infrared signals and also used for remote control detection.
There is a IR detector on the Infrared Receiver which is used to get the infrared light emitted by the
Infrared Emitter. The IR detector have a demodulator inside that looks for modulated IR at 38 KHz. The
Infrared Receiver can receive signals well within 10 meters. If more than 10 meters , the receiver may
not get the signals. We often use the two Groves-the Infrared Receiver and the Grove - Infrared Emitter
to work together.
Grove compatible interface.
Supports 3.3V and 5V supply voltages.
Application Ideas
Remote Control of robots, relays or other things
Mechanic Dimensions
20mm by 24mm
Hardware Installation
Connect the Transmitter module to Digital I/O 10 of the Grove - Base Shield on the receiving arduino.
The demo below is the IRrecvDemo.pde example provided by the IRremote library.
Download and unpack into arduino/hardware/libraries in your arduino installation.
* IRremote: IRrecvDemo - demonstrates receiving IR codes with IRrecv
* An IR detector/demodulator must be connected to the input RECV_PIN.

Serial.println(results.value, HEX);
irrecv.resume(); // Receive the next value
