I was trying to figure out if VCR buttons can be triggered with PNP transistors?
I soldered wires to the non-negative sides of 10 buttons on the VCR which when pressed, create pathways to ground.
With the 10 wires on the positive sides of each button, would I be able to connect each button to ground with a PNP or NPN?
I figure with a PNP, if the base goes low, it could connect collector with the emitter, but also thought maybe applying voltage to the base of NPN's it could connect the collector to ground as well.
It seems a little tricky but I have both Tip31c and Tip32c transistors. I'm having trouble understanding how to simulate a button press with a transistor.
Thanks for your help.
