How the 1x4 Membrane Keypad Works
The keypad contains four individual membrane switches connected through a common pin, requiring only five connections to your microcontroller. Each button can be read independently as a digital input, making it ideal for simple control interfaces where only a few buttons are required. Common applications include menu navigation, volume controls, directional buttons, and custom function keys.
Pinout & Wiring
The 1x4 Membrane Keypad uses a simple 5-pin ribbon cable. One pin acts as the common connection, while the remaining four pins correspond to each button.
| Pin | Function |
|---|---|
| 1 | Common |
| 2 | Button 1 |
| 3 | Button 2 |
| 4 | Button 3 |
| 5 | Button 4 |
Connect the common pin to either GND or VCC depending on your circuit design, then connect each button output to a digital input on your Arduino, ESP32 or Raspberry Pi. Internal pull-up or pull-down resistors can be used for stable button detection.
