I am hoping to read 64 E49 hall sensors, in an attempt to make an e-chess board.
Problem is when I set up more than one hall sensor < I still only get a rea d from one. A0 gives data, but A1-A7 just dont respond. does anyone have suitable code that would help ?
Most likely a circuit error or wiring problem.
Please post a schematic diagram, with pins, parts and connections clearly labeled. Hand drawn is preferred. Also state which Arduino you are using, and post the code, using code tags.
