Let there be light! In this tutorial we'll build a basic magnetic levitator. This guide will go over some of the theory, how to use a magnetic field sensor, and how to use one to build a basic levitation circuit. Finally, we'll go a bit further and build a wireless power floating light.

Required Materials

To follow along with the examples in this tutorial you will need the following materials:

The other parts used that we don't carry are:

  • Analog Hall Effect Sensor
  • 1N5401 Diode
  • 1mH Inductor

Required tools

The tools needed for this project is a multimeter and soldering iron, but having access to an oscilloscope will help with testing as well.
