I came across this circuit on google. It controls motor speed by simple flip-flop that gives a PWM signal.
The question is can this be used as a servo control ?
first use 5 volts supply instead of 12 volts ...then by replacing the 3RD NPN transistor with a servo. the + goes up, the - goes down and the signal feeds from the flip flop...can we do that ??
