I am trying to figure out if I can use a Teensy for a project I am working on where I switch a mosfet to control a 12vDC air pump. I would like to use a single power source, such as a 12vDC Barrel Plug/Jack (https://www.adafruit.com/product/798), but I am unsure of how I would connect the teensy to this power source, or if I am just looking at a problem waiting to happen.
Take Care,
Mike
