Before we begin ensure all LEDs are connected the right way around. The short lead goes on the right and the longer on the left.

We will be adding the resistors later so be sure not to plug in any power yet as it could damage the LEDs

The image below shows the long and short leads, and then the second image shows how they should be wired, third showing the order.

TIP! Ensure that yu have the LEDs spread across from the 5 column bit to the two column bit or else they will not work and you will have a short circuit.
