Hi all...
I'm doing a project at the moment which involves PIC (specifically a 16f877). As one of its functions, I am wanting (or hoping!) it to turn the volume of my Sony Hi-Fi (DHC-MD333) up and down remotely. I'm at a bit of a loss as to how to go about this... I'm assuming that it can be done by using an IR LED/Bulb that is turned on and off in a certain sequence (which should be pretty simple with an 877 - let me know if it isnt!!).
The part which im stuck on is what the code sequence would be for volume up and volume down, and at what speed/frequency (Im assuming that it has to be at a certain frequency).
If anyone would be able to shed some light onto this, I would be extremely grateful.
Thanks for your time,
Ferg
