Magnet levitation toy using Arduino. Cheap and easy to make!

I found the Arduino Leonardo to be a great way to manage my CNC machine with little programming effort.

Standalone Arduino 6-channel triggered oscilloscope with optional freeze frame.
A better and cheaper alternative to a climate-dependent control for your central heating boiler. Especially if you have in-floor heating.

Do not forget!
The limite for all, TIP120, TIP121 and TIP122 are 65 WATTS.
I found an other levitator in the site and it have a PID function too.
The code is more complex, but have a lot of comments and default values.
The goal is the same: a TARGET(know value), kP, kI, kD and an INTERVAL.
Maybe it can help everybody with trouble with my PID version.
Kind regards Juan
I saw the datasheet for both, tip120 and tip122 and I believe it will work fine.
The difference is that the tip120 supports up to 60V in the pins 1-Base and 2-Collector and the tip122 up to 100V in the pins 1 and 2.
All others parameters look be the same: https://www.onsemi.com/pub/Collateral/TIP120-D.PDF
Same for the tip121, up to 80V(DC) in the pins 1 and 2.
A safety voltage for "normal humans" is up to 48V(DC).
100V is a lot of voltage(DC) please be careful.
Kind regards Juan.
