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.
- Goal:
- 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
- Datasheets
- HBridge_L293D.pdf - H-bridge for driving a DC motor
- Optocoupler_A847.pdf - Optocoupler to optically isolate your H-bridge
- HexInverter_74HC04.pdf - Inverting chip to digitize optocoupler output
- Optoreflector_OPB740.pdf - Optoreflector to detect lines or color
- Optoreflector_QRE1113.pdf - Optoreflector to detect lines or color
- Phototransistor_SFH310.pdf - Phototransistor to detect lines, color, or laser reflections
