Hello,

I've mount a levitation module I bought on Banggood. When I present a magnet on the top, I've only a lighting LED and nothing more. The potentiometers don't seems to act anything.

Someone can help me?

There's two jumpers and I saw in another version of module that's can be used for plug an amperemeter to measure something, but what value?

I have a similar module with only 4 magnet sets and found it EXTREMELY tricky to get working Both pots have to be close to optimum to have any chance of proper operation and I had to resort to some exteral indicators to tell me the proper positions If incorrectly set the power transistors will get VERY HOT so I replaced the series links with a couple of 12V 6watt car bulbs The two pots are first adjusted to give minimum brightness with power switched on by positioning the suspended magnet in a central position Use some cork placemats to protect against runaway movements and hold the suspended magnet central with a non ferrous ring I used a short length of aluminium tube just larger than the target magnet around Once both set to minimum the links can be replaced and the ring used to move the target about the central position where it should attempt to rise If it doesnt rise then probably the Z sensor is facing the wrong way and you will need to correct that Check by firmly holding the target central and lowering towards the solenoids as the target gets close you should feel the repulsion power should switch on before you feel the repulsionAs a matter of interest I have prepared full schematics of both of my boards using Eagle 920 These are drawn so that the circuit functioning can be understood unlike other schematics I have seen for these modulesOldHand
