Had working in under 10 minutes. *by D***S on Reviewed in the United States on April 16, 2013* I bought this to test out the microphone capabilities of my Arduino Uno board. It comes in a small sealed package with ZERO documentation. However, the board is labeled and it has 4 pins; Analog Out, Power, Ground, and Digital Out. I connected the Power to 5V on the Arduino, Ground to Ground, and Analog to Analog 0. I opened up the Serial Monitor and I could see it picking up sound. If I clapped or shouted into the mic, the output numbers would raise dramatically.I had to google some test code for the microphone (I'm a newbie to all this,) but in under 10 minutes I had found a very simple code that allowed me to set a threshold level for the microphone which would turn LED's on/off once the threshold was passed. Hooked up two red LED's and I had them turning on when I would speak; turning off when there was silence!The microphone will work without a pre-amp; but it does seem like the detection is pretty low without it. I can definitely make the output jump by shouting into close; but I bet with a small pre-amp coupled with it you could make it pick up quite a bit.Would recommend this for testing; not sure how this would hold up in a real world project. Definitely works; google examples of the code (I found the working code on the Arduino dot cc website.) ### ⭐⭐⭐⭐ No documentation needed! *by N***N on Reviewed in the United States on July 1, 2014* WITH ANY EFFORT WHATSOEVER THIS WILL WORKI bought this to make an audio-responsive LED setup. It comes with no documentation, but just reading the board tells it all: power to +, ground to G, analog output from A0, digital from D0.Sensitivity isn't great, but it works as a basic sound sensor. I'll be trying more advanced analysis of incoming signal later; math ability is currently a constraining factor.My sketch consistently gets the LEDs to blink along with music. The mic is most responsive to the bass, so I put it near a sub. Play with the threshold value as needed. Sorry it's a bit messy, I'm working on a few other aspects currently so some things are just sitting there.Example video: https://www.youtube.com/watch?v=4rlYRWBTKIM&list=UUOY0wkoxYrjGluAAY-eQRLQ (notice ambient noise is blocked out with proper threshold value and mic placement)Sketch:// initialize LEDsint ledR = 3; // redint ledY = 5; // yellowint ledG = 6; // greenint leds[3] = {ledR, ledY, ledG}; // led array// setupvoid setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600); // set LED pins as output for (int k = 0; k < sizeof(leds) - 1; k++) { pinMode(leds[k], OUTPUT); }} //setupint i = 0; // indicates first iteration of main loopint thresh = 30; // dummy valueint duration = 100; // default duration of LED blink// mainvoid loop() { // read analog mic input int micRawSignal = analogRead(A0); if (micRawSignal > thresh) { Serial.println(micRawSignal); } // check if value exceeds threshold if (micRawSignal > thresh) { // turn on LED analogWrite(ledR, 250); analogWrite(ledY, 250); analogWrite(ledG, 250); delay(duration); } else if (micRawSignal < thresh) { // turn off LED analogWrite(ledR, 0); analogWrite(ledY, 0); analogWrite(ledG, 0); } // else} // main ### ⭐ Does NOT work. HOoked it up, analog output ... *by R***Y on Reviewed in the United States on November 5, 2014* Does NOT work. HOoked it up, analog output stayed at 1.7V and never moved no matter how loud I yelled at it. It didn't want to sense my loud anger that I have to demo something tomorrow. I should have never bought from a company that idolizes Thomas Edison. I wish I checked their website before I bought. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/5578914-zitrades-high-sensibility-microphone-sensor-module-fit-for-ky-037](https://www.desertcart.pt/products/5578914-zitrades-high-sensibility-microphone-sensor-module-fit-for-ky-037) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
