Each level the target moves faster and you are moved further away from the target. After 4 levels it ends.
Step 1: Parts
1-Arduino Nano ATMEGA328.
1-Parallax 5 position switch.
1-8x8 LED Matrix
1-470Ω Resistor network
Step 2: Wire it up
Pins D8-13, A0-A2 to the negative of the matrix.
The 5 Positions switch should be attached to pins A3-A6. The trick here is A6 cannot be made digital, you'll have to read it as analog. No biggie.
