Hi,
I've purchased a led light lamp with a remote control (using IR for trasmission).
I want to control the lamp via my Arduino, so i create a simple IR circut with a 940nm IR Led (100mA forward current) and a 2N3904 for control it. Is not the first time I'm using this circuit, I'm controlling my TV with it and all works very well!
I reversed all button of remote control of led light with irRemote library (GitHub - Arduino-IRremote/Arduino-IRremote: Infrared remote library for Arduino: send and receive infrared signals with multiple protocols) and an IR receiver led. The library told me the remote control using NEC protocol, and it's confirmed from the reading of raw IR code.
After that I've tried to send code to led light with sendNEC() function, but nothing happened. I also tried with raw code (registered from light remote control) as AdaFruit example for Nikon remote control (Making an Intervalometer | IR Sensor | Adafruit Learning System), but nothing happened.
Only for troubleshooting: I checked with a digital camera that the IR Led emit the pulse and also i checked that the code is real of 32 bits as irRemote library said
What's wrong?
I need to try different 850nm IR LED or a IR Led with a forward current of 1A (peak)?
