the resistors where do i need to place them on the board ?
OK so I do have the Nano also (attached a photo)
also I pretty good in soldering (attached a photo)
now what how do I need to connect them because I tried googling this and its not working there are tons of videos on YouTube but I could not understand them because they are talking about difference situations and parts.
is there anyway to see somewhere a plan like the attached photo?
Since you are having the magnet drag a metal ball, you could build a track for the ball that has contact pads along it, and use the ball itself to make the connection between the pads to indicate its position along the track. Simple way would be to have one side of the track lined with a foil strip connected to ground, and on the opposite side of the track have 20 short sections of foil connected to 20 inputs...
