Flip fllop based touch on touch off switch
I tried the right most circuit in Multisim and it worked.
In place of the relay and diode I had a 120R resistor with the gate pf logic FET connected to the collector of the transistor.
Then I had an LED setup in the drain/source circuit of the FET.
But when I tried it on my bread board for real I could not get it to work.
Have I perhaps I wired in the FET incorrectly?
