LCD Keypad Shield for Arduino

The LCD Keypad Shield for Arduino combines a 16×2 character LCD display with a 5-button keypad interface, making it a perfect user interface solution for interactive Arduino-based projects. Designed to sit directly on top of an Arduino UNO, Mega, or Leonardo, this shield provides both display and navigation functionality in a compact footprint.

Whether you’re building a home automation panel, sensor data monitor, or robot control system, the shield eliminates the need for separate LCD wiring and push button connections. The 16×2 display shows system status, menu options, and sensor values, while the five buttons (Up, Down, Left, Right, Select) allow for user input and navigation—ideal for embedded menu systems.
