    Best technique for supplying different voltages from one battery source

    Never mind, I should know better. Can't beat ohms law.

    Best technique for supplying different voltages from one battery source

    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...

    Best technique for supplying different voltages from one battery source

    Cool, that gives me some options to investigate. Thank you both!

    Best technique for supplying different voltages from one battery source

    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...
