    Nice Keypad, 12 keys will be served by one analog input line only. An additional IRQ signal would be helpful. Might be added in a future improved version perhaps?! I generated it by an opamp (comparator) which goes low if there is an output from the Keypad.

    Is working well, i tested it with Arduino, you`ll save a lot of inputs, but if you wanna use it in a box, will be a hell of a work to make the mask :D

    Does what it's made for, produced fine, arrived in good condition. One thing could have been solved better: a 4th contact, used for interrupt at the Arduino - so you have to do polling...

    Excelent keyboard! Allows the use of just one line and also the possibility of remote use through a current loop circuit just over 2 wires
