Hello,
I have read these forums for over a year and have yet to make a post. I've enjoyed reading all the posts and I am amazed at how helpful the community is especially some the senior members, this site is an incredible resource.
Well enough of an introduction here is my situation. I want to start actually building some of the circuits I have been studying. Recently in my digital logic class we built a PWM circuit using an Altera DE1 board and AHDL code to control the speed of a computer fan. What I want to do is build the same sort of circuit but use a 555 timer in astable operation to provide the pulse and a potentiometer as RA to control the duty cycle of the pulse. The output would drive a transistor acting a switch to handle current needed by the motor. Before I get to deep into the weeds with this project I just wanted to know if i was on the right track.
