Controlling a ( or some) device(s) via IR
-
Hello all,
Having been a happy vera3 and a bridged lite owner I was still missing some options. I am so happy this arduino stuff came available. I recently build an actuator to controll my floorheating.
The second device I would like to make is a device which at least switch off my mediabox via IR. It would be nice if it is possible to also controll some functions on my television ( Samsung) as well , like switching on.
For this project I have ordered a Arduino nano and this IR shield http://www.ebay.de/itm/400602576265?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
And offcourse a 2,4 Transceiver Module.
Next week when I am home I will put this together on an Arduino UNO for testing.
When it is working , it will be nice to also include a temp sensor on it , a humidity sensor, I read somewhere , someone is working on a air-quality sensor.But first the IR-bit.
This is the sketch from the "build" area of this website:
// Example sketch showing how to control ir devices // An IR LED must be connected to Arduino PWM pin 3. // An optional ir receiver can be connected to PWM pin 8. // All receied ir signals will be sent to gateway device stored in VAR_1. // When binary light on is clicked - sketch will send volume up ir command // When binary light off is clicked - sketch will send volume down ir command #include <MySensor.h> #include <SPI.h> #include <IRLib.h> int RECV_PIN = 8; #define CHILD_1 3 // childId IRsend irsend; IRrecv irrecv(RECV_PIN); IRdecode decoder; //decode_results results; unsigned int Buffer[RAWBUF]; MySensor gw; MyMessage msg(CHILD_1, V_VAR1); void setup() { irrecv.enableIRIn(); // Start the ir receiver decoder.UseExtnBuf(Buffer); gw.begin(incomingMessage); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("IR Sensor", "1.0"); // Register a sensors to gw. Use binary light for test purposes. gw.present(CHILD_1, S_LIGHT); } void loop() { gw.process(); if (irrecv.GetResults(&decoder)) { irrecv.resume(); decoder.decode(); decoder.DumpResults(); char buffer[10]; sprintf(buffer, "%08lx", decoder.value); // Send ir result to gw gw.send(msg.set(buffer)); } } void incomingMessage(const MyMessage &message) { // We only expect one type of message from controller. But we better check anyway. if (message.type==V_LIGHT) { int incomingRelayStatus = message.getInt(); if (incomingRelayStatus == 1) { irsend.send(NEC, 0x1EE17887, 32); // Vol up yamaha ysp-900 } else { irsend.send(NEC, 0x1EE1F807, 32); // Vol down yamaha ysp-900 } // Start receiving ir again... irrecv.enableIRIn(); } } // Dumps out the decode_results structure. // Call this after IRrecv::decode() // void * to work around compiler issue //void dump(void *v) { // decode_results *results = (decode_results *)v /*void dump(decode_results *results) { int count = results->rawlen; if (results->decode_type == UNKNOWN) { Serial.print("Unknown encoding: "); } else if (results->decode_type == NEC) { Serial.print("Decoded NEC: "); } else if (results->decode_type == SONY) { Serial.print("Decoded SONY: "); } else if (results->decode_type == RC5) { Serial.print("Decoded RC5: "); } else if (results->decode_type == RC6) { Serial.print("Decoded RC6: "); } else if (results->decode_type == PANASONIC) { Serial.print("Decoded PANASONIC - Address: "); Serial.print(results->panasonicAddress,HEX); Serial.print(" Value: "); } else if (results->decode_type == JVC) { Serial.print("Decoded JVC: "); } Serial.print(results->value, HEX); Serial.print(" ("); Serial.print(results->bits, DEC); Serial.println(" bits)"); Serial.print("Raw ("); Serial.print(count, DEC); Serial.print("): "); for (int i = 0; i < count; i++) { if ((i % 2) == 1) { Serial.print(results->rawbuf[i]*USECPERTICK, DEC); } else { Serial.print(-(int)results->rawbuf[i]*USECPERTICK, DEC); } Serial.print(" "); } Serial.println(""); } */
But how does it work??
If I understand correctly , when I point my ( original) IR-transmitter of the mediabox to the IR reciever ( which is connected to pin 8 , the signal will be stored somewhere on VAR_1 , I expect I can see this somewhere on the GUI of my vera3
This IR-code has to be copy-paste in the sketch.
Here:
if (incomingRelayStatus == 1) { irsend.send(NEC, *0x1EE17887, 32*); // standby } else { irsend.send(NEC, *0x1EE1F807, 32*); // switch on
How am I doing so far??
