Step 6Solder the Potentiometers
To solder the potentiometers, first solder the positive power to one of the outside leads (each pot has 3 leads, one for each end of the resistor and one for the changeable middle). Solder the negative to the other outside lead and a wire going between the corresponding analog in on the microcontroller, and the middle lead. Do this for each pot.
What side you solder the positive and negative lead on matters, it affects what way you turn the pot to move the paddle up or down. The best way to figure what side to solder it to is to solder the positive lead on the bottom when the 3 pot leads face the display from the side they will be mounted on. Or just guess and change it later.
This is also a good place to solder the speaker, attach one side to pin 15 on the microcontroller and the other to ground.
