I've purchased 4 cheap LED controllers from China for controlling 20m LED stripes. After setting the system up, I encountered the problem that at least 1 of the 4 LED controllers doesn't respond to the signal from the IR remote.
This is a real problem if I want to turn them off, because 1 out of 4 doesn't turn off and if I press the ON/OFF button again, it may turn off - BUT - the other 3 LEDs turn on again.
So I had the idea to remove 3 of the IR antennas and only use 1 IR antenna for all 4 LED controllers.
Here's the schematic for this:
The problem: It doesn't really work (well it did for ~10 minutes). Now the LEDs are not lighting up anymore.
Is my circuit wrong or have my LED controllers gone broken? (The LEDs are fine - i tested it with a different LED controller)
