Step 1: Parts

Picture of Parts
All of these parts could easily be found on amazon or even Maplins if you are willing to spend a lot on relatively cheep components!

- 24 Super bright white 12000mcd 5mm LEDs

- 1 Arduino

- 5mm drill bit

- drill

- saw

- wood. A piece 60 cm long is about right although you can go larger or smaller. It doesn't matter how wide it is.

- wire

- solder and soldering iron

- saw

- hot glue and got glue gun

Step 2: Cut The Wood

Now you are going to want to cut your piece if wood to length. 60mm long is best and the width does not matter. Preferably smaller.

Step 3: Drill The 5mm Holes For The LEDs

Now you are going to want to roughly drill 6 sets of 4 holes all along your wood.

Step 4: Hot Glue Your LEDs Into Place In There Holes In The Wood

Step 5: Solder All Of The LEDs Negative Leads Together To Create One Ground For All Of The LEDs

Now you are going to want to solder all of the LEDs negative (-) leads together to make one ground wire for all of the LEDs.

Step 6: Positive Connections

Now solder one wire to every set of 4 LEDs positives. You would end up with 6 positive wires and one ground wire if you have done all of the steps correctly.

Step 7: Plugging In.

Next attach the ground wire to the GND header on yours Arduino.

Attach the furthest away set of LEDs positive wire into pin 13

Next into 12

Next 11

10 and so on until you get to pin 8.
