Keypad - 12 Button

This is a basic 12-button keypad designed for user input. The buttons are arranged in a matrix format, enabling a microcontroller to 'scan' the 7 output pins to detect which of the 12 buttons is being pressed. Check the examples below for correct pin-outs. You can access various documents like Datasheet, PIC HEX Pad Tutorial, Arduino Instructable, Arduino Keypad Library, Alarm System Project, and Bildr Example.

Using this 12-button keypad is easy. Just connect it to your microcontroller as per the pin-out examples provided. When you press a button, the microcontroller will scan the output pins to figure out which button you've pressed. Make sure to handle the keypad gently to avoid damaging the buttons. Keep it clean and away from moisture. If you want to learn more about it, check out the provided documents like the datasheet and Arduino tutorials.
