Hi,
I have to control the speed of a motor.
After I get the control signal I need to send it to an actuator to change the speed of the DC Motor.
I was thinking to use a circuit (attached image) with a IC 555 and a MOSFET. So by changing the duty cycle of the PWM I will change the speed of the Motor.
The problem is that the circuit is using a potentiometer to do this job, and I want to use the control signal to change the speed. Please, do you have any idea how I can do this??? Maybe the pin 5 of the 555?? Please help me to find a solution, or what kind of actuator I can use to change the speed of the motor?
Thanks for your help,
Macmmt
