Tuote SJS242149. AD Keyboard Simulate Five Key Module. If, for example, 5V is applied to the Vcc terminal, pressing the switch OUT brings different voltage values to the OUT pin according to the voltage distribution of the resistors on the circuit board. If, in turn, the operating voltage is not connected to the OUT pin, there will be different resistance values measured, for example, between the GND pin and the OUT pin.

This keyboard uses an analog input to read the five key state which saves I/O resource for the Arduino. It can be used together with I/O expansion boards to make amazing interactive project.
Five buttons occupy a simulation port and save more resources
Analog variables acquisition, press different keys and output different voltage.
Standard interface that can be expanded in a variety of development boards.
Equipped with screw holes for easy installation.
3 pin I/O connector: VCC, GND, OUT
