Project: DC Motor Speed Control using PWM from Arduino

Description

DC Motor Speed Control using PWM (Pulse-Width-Modulation) from Arduino's output pin 3. Uses a TIP112 NPN transistor to supply current from battery. PWM frequency is 490Hz with dutty cicles between 50 and 255. The dutty cicle value is set by an analog input of a potentiometer. Arduino Duemilanove board.
