When you throw a punch you are throwing a fireball. You might have seen in many movies, heroes with the ability to throw fire balls, - fire benders.
With this arm mounted DIY Arduino project you can be a fire bender, but with extra caution.
A fist performing a punch has a fairly unique acceleration profile that looks like a significant positive acceleration (the beginning of the punch), followed by an extreme deceleration (the end of the punch) within a small window of time (<100ms). That means our Arduino can distinguish punches from normal everyday gesticulations pretty easily!
This solves a major problem, a common man's eager to be a heroic fire bender.
