1 Microcontroller Hands-on Workshop #4 Ahmad Manshad New Mexico State University Institute of Electrical and Electronics Engineers November 14, 2009

2 2 Agenda for Today Quick Review Freeduino motor controller Control servo motor Work on robot

3 3 Today’s Kit 1.Arduino Microcontroller/ USB Cable 2.Breadboard 3.Wires 4.Soldering Iron w/ solder 5.Freeduino Motor Controller 6.DC Motors 7.Servo Motor 8.10K Potentiometer

4 4 Quick Review - PWM  PWM signal is a digital square wave where the fraction of the time the signal is on can be varied between 0 and 100%.  Call analogWrite(pin, dutyCycle), where dutyCycle is a value from 0 to 255.  Use one of the PWM pins (3, 5, 6, 9, 10, or 11).

5 5 Quick Review - Motors Electromechanical device that converts electrical energy to mechanical energy

6 6 Quick Review - Motor Controller Control 2 motors from your Arduino SN754410NE motor driver Board and Arduino pinout: Motor A Direction - Arduino Digital pin 13 Motor A Speed (PWM) - Arduino Digital pin 10 Motor B Direction - Arduino Digital pin 12 Motor B Speed (PWM) - Arduino Digital pin 9
