Infrared remote/communication

a) Target: Infrared remote/communication

b) Hardware List



DFRduino UNO R3 x2



IO Expansion Shield x2



Digital IR Receiver x1



IR Transmitter Module x1

c) Software List



Arduino IDE



Get Arduino library Arduino-IRremote and install it

d) Connect Diagram



IR Transmitter: same as above, Notice: Arduino-IRremote only supports D3 as transmitter.



IR Receiver: connet it to D11 port.

e) Step by Step



Open Arduino IDE



Upload code to the UNO connected with IR Transmitter:

#include <IRremote.h>

IRsend irsend;

void setup()

{

}

void loop() {

irsend.sendRC5(0x0, 8); //send 0x0 code (8 bits)

delay(200);

irsend.sendRC5(0x1, 8);

delay(200);
