[Hack] Connect and Control Polaroid to Arduino

this can be fucking fatal. I would say “do not try this at home”, and i just did. The below images should exactly describe how to hook up a Polaroid camera to an Arduino. The connections are fairly straightforward.

Hook it up to your microcontroller

To hook up a Polaroid to your microcontroller or arduino, you can generally go three ways: 1) Transistor; a bit difficult – this is what i used but I had trouble selecting t he right resistors (>2k ohm didnt work for me) 2) Relay; super easy but draws a lot of current. 3) Opto-coupler; super easy but polarity is important (the way you hook up + and -) This is the general opto-coupler setup (buy this from sparkfun or something):
