Description
This four-key membrane switch keypad with a 1x4 grid is simple to operate and will complement your project well. It contains 5 outputs and 4 keys; use the "Scan Mode" to determine which button has been depressed. Arduino, AVR, PIC, STM, and Raspberry Pi are among the platforms that have been supported.
This low-profile membrane keypad may be placed in almost any place. The four keys are connected in a 1x4 matrix that an Arduino can easily interpret. A flat flexible ribbon cable with a Breadboard compatible 0.1" pitch single row female connector provides the electrical connection.
Specifications:
1*4 Matrix membrane switch with FPC circuit
Single-chip microcomputer extended keyboard
Precise and professional made, stable performance
Pad Size: 68*20mm
Total Length: 107mm
The simplest decoding method requires a digital output for each column and a digital input for each row. The pin count can be reduced by adding a resistor divider network and using Arduino's analog input capability creatively. you can use this Arduino Keypad.h Library Click here to DOWNLOAD it.
