#195 Reverse Polarity Protection using a MOSFET - for Arduinos and more!
Here's a simple circuit that makes clever use of the properties of a MOSFET - only conduct when the gate is sufficiently negative in respect of the Source, regardless of which way round it is connected!

Yes, a diode can protect your circuit from being connected the wrong way round to a battery too, but there is a price to pay for that simplicity.
A better, more efficient way is to use a P-Channel MOSFET (I'm using a PDP0959 but plenty of others are available) but connected so that is looks like it is the "wrong way" round!
I just wish I had invented (and patented) this circuit! This time next year I could be a millionaire!
