This handy keypad with 3x4 matrix buttons can be used to, for example, enter a pin code or set a clock.
The keypad can be read out analogously with only 1 pin. Each button gives a certain voltage.
On the back of the keypad are the numbers of the buttons of the keypad that correspond to the global analogue value that can be read with Arduino (between 0 and 1023)
All buttons are equipped with an attachment so that you can work it neatly. The buttons are quite high and are therefore very suitable for installation.
There are also four 3mm holes on the module for mounting.
