Arduino Library which allows to interface with matrix 4 x 3 phone's keypad as well as 4 x 4.

MicroPython ESP8266/ESP32 driver for TTP229-BSF 16-key capacitive keypad in serial interface mode

4 bar drum pattern manager, beat-maker with Arduino components as an interface.

AVR Calculator

MicroPython library for interfacing with a keypad matrix

This repo has most common drivers with basic application and their simulations on Proteus.

📦 The 8051 4x4 Keypad Interfacing demonstrates how to connect and interact with a 4x4 matrix keypad using the AT89C51 microcontroller. Keypads are commonly used for user input in embedded systems, and in this project, we showcase how to read key presses using Assembly language.
