  • Magnet Levitation with Arduino almost 2 years ago

    Hi!
    99% of the levitation is made by the permanent magnet.
    Not by the electromagnet, the electromagnet just avoid the fall.
    But if the electromagnet is too weak the permanent magnet will fall.
    (may be it is the problem)!
    The pulses are a good signal, all the electronics and the code are working...
    It means the sensor is reading the permanent magnet field and turnnig On/Off the electromagnet.
    I saw the datasheet for the (A1325) and looks good, 5V and it is fast.
    My tip is go for 12V in the electromagnet.

    Great news!
    Thank you.

    Yes!
    You can add or just move the hall effect sensor for the bottom to reduce the interference or increase the precision, but you need change the code.
    I have a new code, where I always turn off the electromagnet before read the sensor.
    I just need time to test all and publish it.
