Keypad to Serial Converter Kit for Matrix Button Pads


This great little board is supplied as a kit, with the PCB, Capacitor, Headers & a Chip programmed with the code, ready to go. Once you have assembled the kit, connecting up a keypad like our 3x4 membrane matrix keypad. will give a character output at 9600 BAUD when a key is pressed.
The keys do not auto-repeat, making key entry easier.

Key output from a 4x4 matrix keypad:


1  2  3  A
4  5  6  B
7  8  9  C
*  0  #  D
When using a 3x4 matrix keypad, simply ignore the right-hand column.

    I wanted to connect a keypad to my Arduinio, but I only had 1 pin left. I called the tech guy at proto-pic and after a discusion about my choised, he offered to design a custom board to make the keypad connect to a serial pin on the arduino. I connected the keypad to the board and the board to my arduino, I have now got a fully working project, using all the I/O ppins on the Arduino UNO.
