Backside of soldered LCD
The LCD was the most time consuming component to solder. After it a three terminal header pin was soldered to the Arduino to supply power, ground, and signal to a servo. Several methods were investigated for the terminal but the header pins will likely be glued in place once the enclosure is printed. A small switch was selected from stocked components. Other switches were available which looked nicer but the chosen switch is very common and has the advantage of being installed from behind the enclosure so it can be soldered immediately, troubleshot, and installed later without having to desolder it. A piezo speaker was taken from stocked components and installed to the Arduino on the buzzer pin. This speaker has not been used before so its output is unknown. Pin 13 was intentionally left unpopulated since this is the onboard LED which can be used for device feedback.
