Arduino Project #10: Buzz Wire Game With 7 Segment LED timer with Arduino UNO

 Arduino Project #10: 

Buzz Wire Game With 7 Segment LED timer with Arduino UNO

 Buzz Wire with Score Counter

After playing around with Arduino just to pass time for a while, I decided to make an enhanced version of the good old buzz wire game that counts your failures and goes nuts if you hit the wire 10 times!

The good old buzz wire game, this time with score counter (as well as indicator lights).
