Northwestern Design Competition

DC2011

Milestone 1

On a button press, read the value of a potentiometer and change the brightness of an LED accordingly using PWM. Note: Do not use an h-bridge or motor as previously assigned.
Due before Workshop 2 on Wed, 2/9.
Sample code from Workshop 1

Milestone 2

Due before Workshop 3 on Wed, 2/23.
Use code from NU32v2: Nokia 5110 LCD and NU32v2: Analog Input to read a potentiometer and print the voltage to the Nokia 5110
Optically isolate a motor and control its velocity based on the potentiometer reading
Do 1 of the following:
- Mount a phototransistor to a laser and detect a cake OR
- Detect a line of electrical tape on white paper with an optoreflector
