I want to make this pwm for controlling motors speed without sacrificing torque. I followed the schematic and put it together on a bread board. But I have never messed with op-amps before, so I don't exactly know how to power it.
here is the schematic.
Here is the link to the site: http://www.michaels-electronics-lessons.com/pwm.html
I really want to make this work. But I don't know where the positive or the negative wire of the power supply should go. Also in the diagram it show a ground symbol with a 0 next to it, what does that indicate?
thank you in advance.
please forgive my ignorance as I'm new to making circuits, but I really want to understand.
