Arduino Magnetic Levitator (PID controller)

Written for the Teensy 3

A demo can be seen here: http://youtu.be/AeTEj5-hTBc

Hardware used in demo:

• Teensy 3.1
• Honeywell SS59ET Hall sensor
• 5 Ohm, 69m, ⌀0,4mm coil
• A decent MOSFET driver (VGS <= Arduino operating voltage)
• 10-15V PSU (add capacitors to cheaper PSUs)
• 200-600uF capacitor over the coil
