IR Switch for Luminara Candle Automation (repost with video, photos and final sketch)
-
anyone know if you can buy these in europe?
-
@korttoma just bought these yesterday on ebay:
I have no idea if this is something useful
Worth a try for 8 dollar?
-
I just received a couple of these:

Looks like they are the same candles as Luminara but cheaper, time to build the IR Blaster and find out if I can use the sketch @blacey provided straight of.

@blacey would you mind sharing how you connected the IR-Transmitters to the arduino? Is this what the Transistor is for?
@korttoma, yes the transistor is used to drive the IR LEDs. It is a standard NPN transistor (NTE123AP) capable of delivering 600mA of current through the collector.
The transistor base lead is connected to the Arduino PWM pin 3 per IRLib, the transistor emitter lead is connected to GND and the transistor collector lead is connected to the IR LED emitters wired in parallel (cathode). It is best practice to place a forward current limiting resistor between IR LEDs anode and VCC but the IRLib drives the LEDs for such short intervals, that you can avoid adding the forward current limiting resistors as I mentioned in the video.
-
Thanks @blacey for the clarification. I sort of overlooked the fact that there was a video, sorry. My consirns was about the current limiting resistor but if you say the IR LEDs can take it I believe you. Thanks again for this project ;)
-
@korttoma - sorry you missed the video ;) I have it on my to-do list to draw a proper schematic for the IR blaster board and the actuator but I just haven't had time yet. I would like to post one in this thread to make it easier for people to build their own IR actuator. Maybe you will get there first ;)

Hello @blacey , I got a question... If I'm going to add another IR into the sketch, how do I go about doing this? So two independent sensors into one. This is what I have done so far. Correct me if I'm wrong. Should I be changing something in IRsend irsend ....?
And is your IR LED connected to Pin 1 or Pin3?

Your sketch looks close but you will need to define separate switchOnIRcode and switchOffIRcode codes for your respective lights. Then in the incomingMessage loop, send the appropriate code based upon the child ID. If you plan to have a large number of child IDs, I would create an array indexed by child ID to hold the on/off IR codes and then simply invoke ir.send() passing the onOffCode[childID] to it. Does that make sense?
Also, I just started another thread for an official IR Blaster board that you might want to review. I plan to provide multiple device support out of the box...

@blacey I think I get what you're saying on #define but don't know how to associate child id with ir code. Do you have a sample or something ?
IR blaster - you working on looks great. Next project is to use that to control my AV system.
Thank you!
@jeylites Here is a quick and dirty example for two switch IR devices... Hope this helps you get started. I will give multi-device more thoughts/elegance for the final IR Blaster.
#include <MySensor.h> #include <SPI.h> #include <IRLib.h> #define NumChildDevices 2 typedef struct IRCode { IRTYPES brand; unsigned long on; unsigned long off; unsigned int bits; } ir; ir childIR[NumChildDevices]; IRsend iremitter; MySensor gw; MyMessage child1Msg(1, V_VAR1); MyMessage child2Msg(2, V_VAR2); void setup() { gw.begin(); gw.sendSketchInfo("Multi IR", "0.1"); // Initialize children devices // 1. Candles (Switch) gw.present(1, S_LIGHT); childIR[1] = {NEC, 0x00ff629d, 0x00ffa857, 32}; // 2. TV gw.present(2, S_LIGHT); childIR[2] = {SONY, 0x0062ff8d, 0x00aff578, 32}; } void loop() { gw.process(); } void incomingMessage(const MyMessage &message) { //Determine the child device uint8_t child = message.sensor; //Get the relay status for the child device int incomingRelayStatus = message.getInt(); //Emit the appropriate IR code to the child device iremitter.send( childIR[child].brand, incomingRelayStatus == 1 ? childIR[child].on : childIR[child].off, childIR[child].bits); } -
I just wanted to confirm that the cheep ebay Luminara "style" candles does work with blaceys sketch "out of the box".

@tbowmo said:
Hmm by cheap, I thought it was below 15$ :)
They are cheep compared to the Genuine Luminara products + I could not find a good suppler for the real thing sending to Europe
Maybe the once @betonishard mentioned earlier in the thread would be something more in your prize range? Would be nice to know if they also work with blaceys sketch though.
