Move It!

Part I

• THEORY: Electromagnetism
  • right hand rule
  • left hand rule
  • Make a small inductor by winding some wire?
  • Show field with a compass? Iron shavings?
  • Transformers (show how to use a signal generator?)
• DEVICES: real-world control:
  • Electromagnets
  • Solenoids
  • DC Motors

Part II

• THEORY: Controlling (high) current w/micro-controller
• DEVICES: H-bridge for direction (make one with 2x SPDT or 1x DPDT switch?)
  • relays
  • power transistor
  • Inductors, flyback, meet ELI the ICE man
  • Protection diodes

Part III

• THEORY: PWM for speed control (view with oscilloscope)
• DEVICES: Arduino motor shields.
• HANDS-ON: Drive DC motors, controlling speed and direction using a motor shield.
