I have watched a few videos on how to connect a mini 5v fan to my raspberry. I am still confused. On my fan I have one red wire and one black wire. Which pin do I connect the red wire to and which pin the black wire. A diagram would help. The videos I watched all seem to differ.

    red is usually positive, black is negative (or ground) ... so red to 5v, black to gnd – Jaromanda X Feb 20 '19 at 5:26
