    Voltage help!
    Anyone have any experience with a peltier?
    Is there a way to switch the voltage direction in a circuit using an arduino?
    If so, what is the best method?

    I'm working on a project for class and I can't tell if something is wrong with the equipment or my set-up because there's no current. The peltier was working before, but now when we try plugging it directly into the 12 volt power source, it can read a voltage across it but there's no amperage going through it and it doesn't heat up.

    If anyone has any suggestions about how to get this to work, I'd be so grateful! This is for a box I'm designing - I need to find a way to use a fan to control the temperature inside the box.
    Thanks so much! :)

    My guess would be you cooked it. Describe your setup.
