I have an old cd/radio and have installed a bluetooth module into it, the only way to activate the audio cd audio lines to the amp is to play a 'silent cd'. The cd is 79.55 seconds long. To play continuous so the audio line stays active is to put the cd on repeat.
Currently the only way to do this is via a remote control code as there is no button on the cd/radio. I know how to capture the remote codes and program that into an arduino, so my question is this.
Can I just send the command via a pin on the arduino without using an ir led and solder directly onto the cd/radio ir reciever pin so that it gets that code?
I just want to use a push button switch to toggle the remote (repeat) command instead of using a remote.
