I am building a project that uses a keypad, currently im using a 3x4 matrix keypad
To add a bit of spice i wanted to make my keypad so that i press a piece of glass, looks a bit more futuristic.
I belive i would need a Capacitive switch, but all the circuits i have found are fairly complex and making 12 circuits for 12 switches would be a big extreme.
anyone got any ideas or know of existing circuits that i could use??
Cheers for the input, i will have a look at this evaluation kit, it might prove useful as i wanted to make me a custom keypad rather than the standard 12 digits, was thinking of an up/down/left/right enter sort of setup.
