Hi Guys,
this is the first time I put a new topic on. I've a simple idea but I don't know how to get started with it.
I'd like to modify a PT2399 delay swapping the time and feedback pot with infrared sensors. I've noticed that normally the IR sensor give a variable voltage in output. How can I substitute a standard pot (with is a variable resistance) with a IR sensor without messing up the circuit?
In the PT2399 for example, pin 6 is normally connected to a 20K pot in order to vary the time repetitions. If I'd want to remove the pot and put an IR sensor there, how should I change the circuit?
Thanks a lot!
