Tap Sensor Module Tap Module KY-031 Electronic Building Block -75577
product detail
Product introduction:
The tap sensor can output a low-level voltage signal when it senses a tap signal. The tap sensor module and the digital 13 interface of the for arduino module come with LEDs to build a simple circuit to make a tap flasher. Use the built-in LED of the digital 13 interface to connect the tap sensor to the digital 3 interface. When the tap sensor senses a tap signal, the LED flashes and glows.
