Sound Level Meter Project from Jaycar
This sound level meter project from Jaycar is an engaging and educational DIY kit, perfect for electronics enthusiasts and beginners alike. The project is based on the LM3915 chip, which is designed to display audio volume intensity through an array of LEDs. This visual representation allows users to see the audio level changes in real-time.
Key Features:
- Volume Indication with LEDs:
- Yellow and Red LEDs: Indicate maximum volume levels.
- Green LEDs: Light up for medium sound levels.
- Mono Jack Connection:
- The kit includes a mono jack that can be connected to an audio source, such as an FM radio. As the volume of the audio source is adjusted, the LEDs visually display the intensity of the sound.
Step-by-Step Assembly:
In the accompanying video, you will find detailed instructions to guide you through each step of building the project. From connecting the components to calibrating the LEDs, the video ensures that you can successfully complete the project, even if you are a beginner.
