How It Works – Circuit Overview
The Bluetooth module's red terminal supplies 5V power, while the white terminal connects to the left and right speaker channels. Red wire = positive (+); black wire = negative (−). The sound-activated LED circuit consists of a power supply circuit, microphone amplification circuit, and LED indicator circuit. The microphone captures audio signals, amplifies them through transistor Q1, and drives the LEDs — louder sounds produce brighter, faster-flowing light patterns for a stunning audio-visual display.
Wiring Quick Reference
- White terminal → Speaker connection
- Red terminal → Power supply connection
- Bluetooth pairing: Enable Bluetooth on your device → Scan → Select XC046 → Connect
