Step 4Drill the holes and populate the board
You will notice that I have created the board with the trace on the top side instead of the bottom of the board. I did that because it makes it easier to solder the headers onto the board and have it sit flat against the arduino.
I started with the resistors when populating the board. Bend the leads as close to the resistor as possible and put them into the board and solder and clip the excess leads. You can next install the headers or the LED's. The LED's have to be mounted proud of the board in order to solder them in place so I would suggest doing them last but since the component count is so low it doesn't really matter which parts are installed first.
