Step 5: Hook it up
Now that you have everything prepared, you can start hooking and soldering everything together. I like to start by soldering everything in place that I can before putting the main board in. So you can start by hooking the battery clip to the input and ground of the illuminated switch. Then you can hook the output of the switch up to R1 and R3, and hook R1 and R3 to R2 and R4 respectively. You can also go ahead and solder one of the wires from the "fire" switch to the audio-out jack as well as the ground from the battery. Once you have that done you just need to put in the board you made and hook the X and Y axis series of potentiometers of the audio out to the remaining wire for the "fire" switch, and the 9 volt input to the power switch.
