Description: For this lab, I built a circuit which takes input from a potentiometer and outputs values to a DC motor. Because the motor vibrates and spins, I decided to attach a thin cardboard cutout to the rotating axis, creating a functional makeshift fan to cool yourself off with!
Components:
1 Arduino Uno
1 Breadboard
1 potentiometer
1 motor
1 diode
1 transistor
1 resistor
