FireDarts - Arduino Dart Machine

Hello,

This is a project I've finished a while ago. You can see the previous version in action here:

Basically I build a software that manages score and works like a bar dartmachine, alongside a electronic circuit that communicates with it (all with an arduino, but it can work with other microcontroller). You can download the final version in the link bellow and you can use it if you want.
Many thanks!

How do you sense impact?

I did it with a vibration sensor. I tried two different vibration sensors and the most effective was with a piezo disk. If you want try to assemble one dart machine I can also give you my arduino code, but that depends on the hardware you have (but you can get an ideia on how it works).
