DIY Stream Deck with the Pi Pico and the Pimoroni RGB Keypad

4x4 matrix keypads integrated into ESPHome/Home assistant able to control Nuki locks as well as your Home Assistant home alarm.

2nd Semester CCSE Engineering Department - Sensors Project (Smart Home)

Tic-Tac-Toe game with AI implemented on a Raspberry Pi Pico board and a 20x4 LED display.

stm32f303vct6-discovery garland with shim, different regimes, keypad(3 buttons)

This implementation allows reading a 4x4 keypad without an external IC encoder (like the 74C922/23). It performs the same function as the IC, but in a simpler form. The module can be used in various projects, such as a calculator. A detailed explanation is provided in the README file.

MatrixKeypad 4x4

8x2 LCD display and 4x4 Keypad were connected over an Arduino. This is an Arduino program that verifies if a user entered the correct Pin. There are only 3 attempts after which will have to wait for 10 mins to re-enter the password.

Password Based Security Door Lock using ATMega162 Microcontroller

MotorLock is an Arduino-based project that controls a DC motor using a keypad and LCD display. The motor will only work if the user enters the correct password.

This is a simple Arduino code for a calculator designed by connecting hardware peripherals which includes 16*2 LCD-module, 4*4 Keypad-matrix. This code performs simple to moderate computations like addition, subtraction, multiplication and division.
