Circuit or Method for controlling RPMs of DC Motor
March 14, 2013
Hi... I'm looking for a way to control (vary) the speed of a small toy DC motor.
I started off trying the simple method of just adding a 5K potentiometer to
the circuit but that does not provide much adjustment. I'm using 3 or 4.5 volts
and just looking for a simple circuit that will allow me to regulate the speed from
0 up to full throttle.
thank you in advance for any suggestions or directions to follow.
