I've got some TV remote code here that might be useful for other projects.
Channel up and down turns the lamp on and off:
Here a TV remote controls a servo and makes an LED blink:
They both use the IR remote library found here: A Multi-Protocol Infrared Remote Library for the Arduino
My code is written for Philips, but the IR library can be used for several different remotes. You'll have to change some of the values in the code for other remotes. There's a forum page about the library here: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1251570417
The lamp is plugged into a powerswitchtail. It's a short extension cord with a relay built in that you can turn on and off like you would an LED. Information.com People Search | Free People Finder & White Pages - Locate Anyone
Ingredients for these projects:
1 IR receiver
a 220 ohm resistor for the receiver
the downloaded IR remote library from the link above
powerswitchtail for the lamp or other appliance
The lamp code:
//LAMP CODE
//Channel up turns it on , Channel down turns it off
//Also the mute button can click a second powerswitchtail on or off
#include <IRremote.h>
int RECV_PIN = 11; //connect IR receiver to pin 11
IRrecv irrecv(RECV_PIN);
decode_results results;
int power = 1;
int buttonState = 0;
int lastpressed = 0;
void setup()
{
Serial.begin(9600);
irrecv.enableIRIn(); // Start the receiver
pinMode(13, OUTPUT); //The Powerswitchtail is treated just like an LED
pinMode(8, OUTPUT); //I threw in some code for the mute button also for another powerswitchtail
}
void loop() {
unsigned long codeValue;
