1 × Arduino pro mini Common Ebay purchase.
16 × White LED'S Those where pulled of a useless chinese headlamp i had around.
4 × 200ohm resistors I probably should have used 8 1k resistors but it doesn't make a difference.
1 × Prototype board I used a very low quality prototype board. You shouldn't do that.
1 × On/off switch This just disconnects the VCC pin and turns everything off.
1 × Reset button I honestly don't know why i put that in the project. The pro mini has one of those integrated.
