1. What is a 4x4 membrane keypad?
- The Keypad 1×4 features a total of 4 buttons in Matrix form. This is a membrane keypad with no moving parts. A female 5-pin berg connector is required for interfacing it with your microcontroller circuits.
2. How does 4x4 keypad work with an Arduino?
- The working principle is very simple. Pressing a button shorts one of the row lines to one of the column lines, allowing current to flow between them. A microcontroller can scan these lines for a button-pressed state.
