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!
Here is a video of myself sucking at my own game:
The source code is divided in three files.
In the code, a "grace period" of 500ms is set after each failure. You can modify that to give the player a bigger break after each buzz.
Also something I noticed at the end was that the LEDs are a bit too bright! Feel free to swap the two resistors used on them with stronger ones. Mine are only about 100ohms.
For the ring, I have used the end of a key-chain. The good thing about it is that you can just open it and won't have to navigate all the way back on the wire.
I hope you enjoy my project!
