Magnetic levitation is mainly composed of coils, magnets, Hall sensors, and drive circuits. When the magnet is close to the Hall sensor under the coil, the Hall sensor will output an analog value to the amplifier circuit for amplification when it senses a change in the magnetic field and then perform pulse width modulation through this value. When the magnet and levitating object move away from the sensor due to gravity, the sensor output value increases the voltage duty cycle on the coil and the magnetic force of the coil, thereby pulling the magnet and levitating object. On the contrary, when the distance sensor is very close, the sensor output value reduces the coil voltage duty cycle, and the coil magnetic force is weaker. The magnet and the levitating object rely on their own weight to keep away from the sensor, and the magnetic object is levitated by continuously adjusting the coil voltage duty cycle.

Suspended solids and precautions:
1. After the device is connected to the power supply, the power indicator light on the PCB board is on. Slowly move the float to be tested from the base ring to the bottom of the coil. When it is about 5 cm away, you will feel the force of the float absorbing the coil. At this time, hold it with one hand. The upward force of the float is used to adjust the PCB sliding rheostat on the one hand. When the two forces are almost balanced, stop adjusting the sliding rheostat and slowly loosen the float to maintain its stability. In this way, you can successfully Float the float, slide the rheostat clockwise to reduce the magnetic force, and counterclockwise to increase the magnetic force; the magnetic force can neither be too large nor too small.
2. If it fails to float in place (up to 5 times), it must be energized and cooled many times; otherwise, it is easy to damage the components.
3. Do not float on the kit for a long time (up to 5 minutes); it can easily cause equipment damage.
