First off, the disclaimer: I'm not responsible of whatever you do. You have to know that with a great power comes...bla-bla-bla. Just be careful and remember that electricity reserves respect. While the energy involved in this project is generally safe, it can be fatal (or at least very harmful) given certain special conditions, so just to play on the safe side:
- Never mess with little children or pets, even with their consent, just say no.
- Avoid old or sick people (mainly with a heart condition or with a pacemaker (or a peacemaker gun).
- Remember that using the device on body parts other than the extremities can be dangerous (you never know what nerve are you killing).**
In connection with the Milgram experiment and to avoid any ethical dilemma for the Arduino, I used the LED library; doing this way I fool the Arduino into thinking he is only deploying innocent LED blinks to the players. Arduino is only obeying the evil orders of the authority figure and is not aware of the pain of the players, please don't judge him.
By now, maybe you are wondering: "What's a Q&D-Poor man's-Skinner-Sadist-Jeopardy game?, do I need one?, is it for me?" well, if you are ready to start an epic journey to the world of power, irresponsibility and electronics to create a device capable of make the players learn something by the always effective power of pain and shame... you might be ready to receive the knowledge.
Given that, let's continue with the description on the next step.

**For those faint of heart or just coward (like me after too many accidental shocks while working on this) I designed an alternate feedback system . Instead of shocks it just shares vibrations with a vibromotor, it is still fun if you place it in body places where the vibration results very uncomfortable, like over the inferior part of the eye, behind an ear or whatever weird place you can imagine.
