Arduino Lecture 3 - Making Things Move and AVR programming

  1. 1. Making Things Move and AVR Programming CS4062 - Eoin Brazil - Semester 2 - 2008
  2. 2. Servos and Motors Motion linear or rotary Stepper Servo conversion issues Types DC Servo Gearhead DC Motor Stepper Gearhead
  3. 3. DC Motor 2 Connections Continual spin, given current voltage Reversing current, reverses the direction Increasing the voltage, spins faster, decreasing the voltage, slows the spin High speed but low torque Gearbox can add torque but at the expense of speed
  4. 4. DC Motor Example
  5. 5. DC Motor Example
  6. 6. DC Motor Example
