This is a prototype of one of my upcoming projects. I will be using a big sound sensor(KY-038) module. The sensitivity of the sensor can be adjusted by turning the little flathead screw.
The sensor on the top of the module, performs measurements which are sent to the amplifier to convert them into analog signals.
- Big Sound sensor (KY - 038) module
- LEDs - 03 (Blue ones are better)
- Resistor - 220Ω (x3)
- Solderless Breadboard - Mini
- Arduino Uno R3 / Arduino Nano
- Jumper wires - Male-to-Male (70cm) [x6] || Male-to-Male (10cm) [x1]

Step 1: Setting Up Your Hardware
Step 2: Coding
You will need these codes (first picture) to check for systematic error (background noise).
The second picture shows the codes which you have to upload into your Arduino Uno.
Step 3: Congratulations
You have now completed this project. Enjoy this prototype. If anyone has questions, you can ask me in the comments section below.
