Arduino DC Motor Speed Controller - Hardware Setup. Moving on to component assembly, since our circuit is very simple, we used a breadboard to interconnect the components. We used a power bank to ...

So to overcome these situations, I have come up with an arrangement consisting of an Op-amp, MOSFET, and Arduino, through which I was able to change the gain of the op-amp programmatically. So, in ...
