Pin out

In the current version of the code, this is the pinout, though this can be changed at any time

Device	Arduino Pin
Yellow Button	2
Blue Button	4
Left Pot	A0
Right Pot	A1
Slide Pot	A2
Force Resistor	A3
Solenoid 1	8
Solenoid 2	7
Rapid Solenoid	~6
Servo Scraper	~9
Motor 1	~3

Control Map

Input	Output
Yellow Button	Solenoid 1 Fire
Blue Button	Solenoid 2 Fire
Left Pot	Rapid Solenoid Speed
Right Pot	Motor 1 Speed
Slide Pot	Servo Scraper Position
Force Resistor	Motor 2 Speed

Wiring

Wiring is a little chaotic, but here is a wiring diagram for illustration.

Notes

• Resistor in front of the slide pot 5V of ~50 Ω;
• ~10 kΩ Resistor between the pressure resistor and GND
