IR Switch for Luminara Candle Automation (repost with video, photos and final sketch)

@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.

@korttoma, didn't had time to make the ir blaster yet. So quite frankly I don't know. I am using the remote delivered in the package. It still works by the way, which was surprising for that price. The flicker of the candles is kind of fast, like there is a firm wind in my livingroom.

Wow this is an old topic!
But... I was working on a project and thought that anyone who was looking for a NeoPixel candle example that isn't blocking, well this would be the place. It flickers and flutters like a real candle. The only thing is that the flame isn't illuminated like these nice Luminaras, but I'm too cheap to buy them!
Keep in mind that my example here uses GRB LEDs, but you merely need to reorder the variables in order to get this working for RGB. Plus the Time Library is not Arduino, so you will have to play with that too for a good
randomSeed().It looks pretty realistic with even a single neoPixel in a sheet of A4 paper rolled into a cylinder. I'll post a video when I can.
Have fun with it:
