KY-031 Klopfsensor Modul 3Pin KY-031 Percussion Klopfen Klopfsensor Modul Diy Starter Kit für Arduino
Item specifics： Operating Temperature:-40-85C Brand Name:YX Type:Logic ICs Application:SpeakerSupply Voltage:1.9-3.6VModel Number:DM006 Disclaimer: Knock sensor module and a digital 13 interface, built-in LED build a simple circuit to produce percussion flasher. Interface comes with digital LED, will knock sensor connected digital 3 interface, when percussion sensor senses measure to percussive signals, LED flashing light. Routines source code: int Led = 13;// define LED Interface int Shock = 3;// define the percussion Sensor Interface int val;// define numeric variables val void setup () { pinMode (Led, OUTPUT) ;// define LED as output interface pinMode (Shock, INPUT) ;// define knock sensor output interface } void loop () { val = digitalRead (Shock) ;// read digital interface is assigned a value of 3 val if (val == HIGH) // When the percussion when the sensor detects a signal, LED flashes { digitalWrite(Led, LOW); } else { digitalWrite(Led, HIGH); } }
