Magnetic levitator shield for arduino nano.
This shield is for use with ojbect:

Ekobots - Levitator with arduino.http://www.thingiverse.com/thing:1392023

You can order the shield at:https://oshpark.com/shared_projects/kxH3Ak1b
It was published in OSH Park by Thingiverse user krwynn:http://www.thingiverse.com/krwynn/about
Thanks!
All you need:
1x Arduino Board (Nano to use the shield);
1x Electromagnet - ZYE1-P25/20 12V, 25mm diameter, 20mm height (ebay $7.00);
1x Linear hall effect sensor - 49e (ebay Kit 5 - $1.50);
1x Magnet cube 10mm (ufo_1) or magnet sphere 10mm (ufo_2);
1x Darlington Transistor NPN - TIP120;
1x Resistor 1K ohm;
1x Diode N4007;
1x Power supply 12V 1A (ebay $2.00);
2x Micro switch;
Arduino firmware:
Levitator.ino - For normal people, with life and girl friend;
Levitator_PID.ino - If you do not have life and girl friend or
if you have any kind of mental disorder, it was made for you... ;-).
I am testing a new firmware with safety mode, it turns off the
electromagnet in case of fall of the permanent magnet.
Working mode:
The switch "+" increase the distance from the electromagnet.
The switch "-" decrease the distance from the electromagnet.

Attention:
See the images to mount the hall effect sensor;
The electromagnet alter the sensor real value for the permanent magnet;
Mount the hall effect sensor as far as possible from the electromagnet;
Use neodymium permanent magnets (it will not work with common magnets);
Use soft wires to make easy the assembly, small box, remember;
That's all folks!
