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

Excellent project. Very useful and well documented.
Nice project. Think about adding a buzzer or a red led. In this way, the smart plant can call for your help. If you want a smarter plant, which can pour in water by itself, check this project: attiny85-plants-care.
The code shown in this project is too simple and controlled by the Serial interface. Look at my project (https://www.hackster.io/M-V-P/attiny85-plants-care-493db9) or those of other hacksters for autonomous systems, based on analog input. Come with new ideas!
