Infrared (IR) Remote

## Infrared (IR) Remote ## Here's the pinout for almost every 3-pin IR Receiver: ![IR REMOTE][1] (Above): a diagram of connecting the receiver to an Arduino. There are many different manufacturers of IR Receivers and some have different pinouts: ![IR Receivers][2] Image courtesy of Alberto Piganti. See: http://www.pighixxx.com/ There is also an easy-to-connect IR Receiver Electronic Brick like this (Down). It can be plugged into a Sensor Shield or YourDuinoRobo1 with a 3-pin cable. ![IR Brick][3] CONNECTION NOTE: The IR Remote Receiver Electronic Brick has 3 pins. From left to right they are: (G) Ground, (V) Voltage, (S) Signal. BUT the marking sometimes vary on the little circuit board. In this photo they are marked G-R-Y. The 3-pin cable in the photo has the typical color code: (G) Ground = Black, (V) Voltage = Red, (S) Signal = White. ![ IR Remote Receiver][4] IR-REMOTE LIBRARY: Note: The following library must be installed in your Arduino installation for this to work! https://github.com/shirriff/Arduino-IRremote Below is the IR Remote Control Kit connected to a YourARDUINO with a 3-pin cable. On the right is the detail of the way the IR Receiver is carefully plugged into Gnd and Vcc on the cable, and the Out pin is insulated with a piece stripped from another wire, the pins are cut off evenly, and Out is routed into the Signal (White) pin of the cable. The software below displays the button that was pressed. ![ir romote][5] Test Arduino Software Sketch for IR Infrared Remote Control [Other Versions below]

If you use the IRrecvDemo Sketch (above) and count the 21 buttons from left to right and top to bottom, the codes received are these: (NOTE: Receiving "FFFFFFFF" means "repeat" if you hold the button down.) ![result][6] [1]: /editor/20160105/568bb29a45918.jpg [2]: /editor/20160105/568bb321b9b9a.jpg [3]: /editor/20160105/568bb3903f59b.JPG [4]: /editor/20160105/568bb3e55ca56.jpg [5]: /editor/20160105/568bb4a806608.JPG [6]: /editor/20160105/568bb578bfd9d.jpg
