Home game, didactic and challenging !!!

Good afternoon, today my daughter asked me for a game and I came up with this quite easy and fun and can play any ..

I'll detail them as I did.

The game consists of walking with a metallic ring the path of a wire without touching them, in the event that they touch an electric circuit is closed and a led light that indicates the contact lights up.

This is the game already finished fixed the wire to the wooden base with two screws.

• I used a USB cable to connect a battery charger, (Black GND and red + cable).
• Resistance 220k
• LED

In the top description I drew (I do not know if this is correct the symbology) the plane so that it is understood a little better.

This is the ring, that if it touches the wire closes the circuit and turns on the light.
**To decrease the difficulty, the hoop can be enlarged.

I hope you can do it and have fun !!!
