Grove - Infrared Emitter
Introduction
The Infrared Emitter is used to transmit infrared signals through an infrared LED, while there is an
Infrared receiver to get the signals on the other side . An infrared LED is like any other LED, with its color
centered around 940nm. We can use the emitter not only to transmit data or commands, but also to
emulate remotes to control your home appliance using an Arduino. The Infrared Emitter can transmit
signals reliable up to 10 meters. Beyond 10 meters, the receiver may not get the signals.

- Page 3 Usage The IRremote library used in the example below relies on using Pin 3 of the arduino for PWM output. For non-IRremote based usage of this Grove, other pins could be used. Hardware Installation Connect the Transmitter module to Digital I/O 2 of the Grove - Base Shield on the receiving arduino. Programming The demo below is the IRsendDemo.pde example provided by the IRremote library.
