Hello,
This is a "touch switch" circuit which I have some questions about..
First, which resistor(s) and capacitor(s) are controlling the frequency at the output of the first flip-flop? R1 & C2?
I tried this circuit and it's working well, the second transistor connects just when I touch the "touch button". I'm trying to make some changes in it in order to make it switches on when I touch the first time, and switches off when I touch it a second time. It's easy to do that using a third D flip-flop, but this requires using two ICs. I'm thinking about a way to do it by editing the circuit around the second part of the IC/the second flip-flop if possible.
the truth table:
