DIY LED board

One of the best thing you can do when learning to create sketches is to create a custom LED board. Using this you can create many simple examples to help you learn.

In our example its a case of 8 LEDs and their corresponding resistors, these can be connected to the pins of the Arduino.

Here is a layout using Fritzing (a great tool for visual mockups)

Now here is our sample which I roughly made on eurocard.
