3x4 Matrix Capacitive Touch Keypad

This is 3x4 Capacitive Touch Keypad. The keypad has 12 buttons arranged in a 3 x 4 pattern. Simple to use, accurate, serial and parallel output available. You can access by serial interface or 4bit parallel interface. The number pad is similar to that found on a telephone. Any of the output can be used for interfacing. The connector uses a standard breadboard pitch (0.100” / 2.54mm) and can be used with the standard Arduino UART Library found in the Arduino IDE. The data is given on the output as the button is touched. It can be integrated with any existing system easily.
