In the world of DIY electronics, Arduino stands as a go-to tool for creators and hobbyists. Today, we're exploring the integration of a 4x4 membrane keypad module with an Arduino, a combination that introduces an interactive layer to your electronic projects.
When working on simple Arduino projects that need basic navigation or input, the AD keyboard module is a handy little tool. It's a 5-button unit that behaves like a directional pad, with four arrow-style buttons and one additional button. It doesn't require any soldering or setup, which makes it a practical choice for prototyping or small projects. You can plug it in and start using it right away, thanks to its three-pin layout and built-in resistors.
