Product Description
Small LED Light Matrix Membrane Keypad With Scratch Coating Polycarbonate
Key Features:
- Compact Design: Matrix keypads are space-efficient and can have various numbers of keys.
- Cost-Effective: They require fewer pins on a microcontroller compared to other keypad designs.
- Durability: Often made from flexible materials, these keypads are resistant to dust and moisture.
Common Applications:
- Consumer Electronics: Used in devices like calculators, remote controls, and appliances.
- Industrial Equipment: Found in machinery for operator input.
- Security Systems: Used in alarm systems and access controls.
How It Works:
- Wiring: The buttons are wired in a matrix format, with rows and columns connected.
- Scanning: The microcontroller scans the rows and columns to detect pressed keys.
- Debouncing: Software algorithms are typically used to ensure that only one signal is registered for each button press.
