Topic: sending remote signals over wire (Read 183 times) previous topic - next topic


so i have this rgb led strip thats powered by usb. its got a little control board (see the hopefully attached picture) and is designed for generic 24 key IR remote (literally identical to the one in arduino starter kits), i want to control the leds from an arduino, is it possible to remove the IR from the board and add pin/jumpers, or should i cut the board down and just use the transistors on the end? i know i could just use an IR led to send the remote signals, but i dont have a spare IR reciever to test with, meaning i would need to remove it from the board to put it onto an arduino to grab the signals anyway. id prefer to use its onboard controller (not just the transistors) because its got a common + and each color on its own ground, meaning all the logic for using them is backwards and complicated. thanks for any help, or at least reading this far

IMHO you would be best to just write your own code for driving the Led's .

Much easier than trying to stick to the limits imposed by another design.

Else you could easily write your own IR receiver/transmitter to send the signals as the original unit is expecting them. With that you could monitor the original remote and then simulate the required stuff as per your needs.

But to add, yes, you could replace the receiver on the original board with a bit of wire driven from your second board. You need to make sure that the levels are right, I would guess levels at 1vptp or less, not sure without measuring, they could be 5v but suspect not.

So to conclude, remove the receiver from the original board, use it on the second board you are making then just pass the required signals via wire to the original board that you generate in your Arduino code.

In short. YES.
