Hey guys, something unanticipated happened and I wanted to verify my results with you. Prior to using the buck converters, I was using a 12v lead acid straight into both the Arduino and magnet with a mosfet in between to turn the electromagnet on. Using that approach, I had measured the amps...
I've got an Arduino that I want to send 9 volts to and a electromagnet I want to sent 13 volts to. The battery source is a 14.8v lipo. I have a handful of step-down buck converters. It doesn't seem elegant to use 2 step-downs to deliver the different voltages, but this is the first time I've run...
