Button Keypad 3x4 module (Assembled) is available to buy in increments of 1
The module has 12 push buttons. You can make usual keypads for enter numbers, symbols, or navigate and selections in the program. There are pull-up resistors of different values for each button. This makes it possible to connect all the 12 keys to taking only one analog port of the microcontroller. The button consists of two parts: a cap, which can be applied to any character, and a transparent cover which can prevent blurring of the text and add light.

Connection:

After connecting power to the module and pressing at least one key contact at "OUT" will stress the appropriate level. Conformity stresses the buttons pressed, you can find out how on the board and in the table below (values are valid out when powered from 5v).
