Hi, can you explain the wiring of the vma431, thanks
You can find the instructions in this link.
I always have the instructions, but I want to know, the wiring, please,
If you are going to use the sketch in the instructions
VCC ==> 5volts
GND ==> Ground
Sig ==> 0
Thanks Wrong_way, can you explain NC pin ?
NC ==> ?
NC= No Connection.
Hope that helps.
Is the polarity changable? Can I reverse magnetic north vs. south by reversing the voltage?
It can’t be done via reversing the voltage on the VMA431 module.
But if you interchange the bleu wires of the electromagnet than can you change the polarity.
This can be changed via H-bridge aslo, see this topic on forum researchgate.net: How to make an electromagnet that changes its polarity after a fixed interval of time? (researchgate.net).
