Once your small circuit has been completed, install all of the hardware onto the project box such as the power switch, volume control, headphone jack and the phototransistor. Hopefully, you will still have room for the battery as well as the small circuit board! I came very close to running out of room, but managed to squeeze all of the parts into the small plastic box.
