I was hoping someone can help, I am trying to interface to a switching box that basically has 6 switches and 3 wires. One wire is ground and the other 2 wires break the 6 switches into two groups and each have a 1ohm, 1k and 10k resistor depending on which switch is pressed.
I am unable to get to the switch box to connect directly to the contacts.
I was hoping there was a simple way of using the 2 channels of resistors to drive 6 relays or something similar? or even a PIC I have a few 16F628A's lying around.
Thanks
