Hey guys..

Can any1 tell me if this would work..?

I have a Logitech Z5500 speaker system, my plan is to crack open the control pod and put this curcuit in between the IR receiver and the Control pod PCB:

The result i want to achieve would be:

- Detecting when the speaker system is in standby mode and when it is on.
- reading the IR signals using the IR receiver in the control pod using the IR-remote library for arduino.
- writing ir signals from arduino to the control pod by wire directly (also using the ir-remote library).
- use the speaker system even when the arduino is unplugged.

all this only using 3 wires between the control pod unit and the arduino.

Cheers guys.

 

No-one who can tell me if this would work?
