Build before class Wed / Thurs
The goal is to build a rotating fan. Here is the circuit wiring, and photos are below
Wiring for Motor Controller
| Motor Controller | Argon | DC Motor |
|---|---|---|
| PWMA | D5 | - |
| AI2 | D4 | - |
| AI1 | D3 | - |
| AO1 | - | Motor wire (either) |
| AO2 | - | Motor wire (either) |
| VCC | 3v3 | - |

Wiring for Potentiometer
- 3.3v
A0- GND
Wiring for Servo
- The wiring colors vary with different servos so look carefully at your documentation
- Many servos will require 5V not 3.3V so use
VUSB
