Hello everybody,
I'd like to ask for help with a circuit for a school project.
The goal of the project is to let a small car roll down a slope, store the potential energy, and release it to go back up the slope.
I will be using a small 5W motor, and a PWM circuit to release the energy gradually. I already built the PWM, but now I do not know how I can hook everything up.
I guess I'll use diodes between the motor connections, and the PWM input (which has a capacitor to store the energy). Now i'll need to do something about the output of the PWM.
Only when the motor supplies 0V, can there be a current between the PWM output and the motor.
Help would be very much appreciated! Thanks in advance,
Alex
