I want to make a cribbage board that will display the score, 0-125, on an LCD screen. I still want to use pegs to move along a path but when the peg is inserted in a hole I would indicate that hole's position (number) to display on the screen. My question is what type of input device can I use to input the peg position? Is there a voltage or resistor or capacitance strip that can I can buy or build to do this? Any ideas greatly appreciated.
