this small project that I have is kind of difficult for me so I would really appreciate your help.
The Arduino (leonardo or Yún, I don't know which works better...) should control:
1) a magnetic field generated by 2 air coils (winding N =800, max current = 0,75A, inductivity = 12mH, effective resistance = 8Ohm) using a power adapter to ensure maximum safety. The field needs to be somehow variable in it's direction and power. Maybe I could use some kind of a potentiometer?
2) a hall sensor that measures the magnetic filed. I voted for Allegro A1301/1302 because it allows ratiometric linear hall effect sensinc and is pretty easy to use.
The measurement output needs to be visualized on the computer. I found a basic code for that but have no idea if this is enough
The whole project is about showing students the secrets to magnetic fields while using different kind of materials that are in contact with the field.
It would be great if you can help me to get this project started.
Thanks and Regards,
