Introduction: Arduino Sound Sensor With LED
A very simple Arduino project with a sensor that detects sound and light up an LED.
Step 1: Gather Materials
Arduino Uno - x1
Male to Female Jumper wires - x3
Any Color LED - x1
USB - Arduino Port Cable - x1
Big or Small sound sensor - x1
Step 2: Assemble Circuit
AO (on sound sensor) to Analog Pin 2 on Arduino Board
+ (on sound sensor) to 5V on Arduino Board
GND (on sound sensor) to GND on Arduino Board
LED short leg to GND on Arduino Board on opposite side of wire connections. Long leg to digital pin 13 on the Arduino Board
Step 3: Write and Upload Code
Here is the code:
Plug cable into Arduino Board and upload the code
Step 4: How to Use the Project
Once you have uploaded the code to your Arduino board, if assembled correctly, a red LED should come on from the sound sensor. When you clap or make a noise the LED should come on. If this does not work, you can use a flat head screwdriver to adjust the sensitivity on top of the blue box on the sound sensor.Once this is done and you clap or make noise, the LED should light up.
