For example, you can use it to make a … It can be used to detect whether there's sound (like the sound of clapping, noise, etc) surround or not and output the sound strength of the environment. After all have been checked and illuminated if necessary, all are turned off in the opposite order to give a rise and fall effect. Arduino is an open-source electronics platform based on easy-to-use hardware and software. Sound sensors also tell you the sound “level.” The best known example of a sensor that can measure the sound level is the decibel meter, but a baby alarm can also register the sound level. soundSample = analogRead(soundPin); The sound sensor converts sound to voltage and that is what comes through the analogue channel. digitalWrite(firstLEDPin+i,LOW); All Rights Reserved. for(int i=0;i A0 arduino Sound sensor VCC -> vcc led strip Sound sensor GND -> GND led strip And one more thing. … The Honeywell 94X Series Ultrasonic Distance Sensors, for example, offer enhanced sensing range capability.
