Musical Fountain Water Controller Variant 4 Kit with Arduino Mega + Relay
Musical Fountain Water Controller Kit — Synchronized Water Jets & LED Rings with Arduino Mega and Relay
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform any pool, basin, or indoor water feature into a musical fountain where each jet pulses in sync with the music’s beat and illuminates in vibrant colour. This advanced kit gives you the hardware to build a professional-grade display for events, exhibitions, or personal art installations. No more hunting for components that may not work together — everything is pre-tested as a system.
What You'll Build
You’ll assemble a control unit that drives 8 solenoid valves, each triggering a water jet, and 4 LED rings (24 LEDs each) that light the jets from below. The system picks up live audio through the MAX9814 microphone, extracts the tempo in real time using Arduino libraries, and sequences the valves and lights accordingly — creating a hypnotic water-and-light performance that responds to any music you play.
What You'll Learn
- Real-time BPM detection from microphone input using the MAX9814 amplifier and Arduino DSP libraries
- High-current solenoid valve control with relay modules and flyback diodes for safe switching
- Addressable LED ring programming with the FastLED library to produce beat-synced colour effects
- Power distribution and noise filtering for mixed 12V/5V systems, including capacitor smoothing on supply rails

Who This Kit Is For
Professional event decorators seeking to add water features to their lighting portfolio, final-year B.Tech ECE/EEE students at VIT, BITS, NITs, or IITs building a capstone project, and sound-and-light engineers working on permanent art installations. The advanced hardware and pre-validated code base remove the guesswork, so you can focus on creative fountain choreography and not on debugging component mismatches.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.

How does the kit synchronize water and light to the music?
The MAX9814 mic amp captures the audio signal, the Arduino Mega runs a BPM-detection algorithm using a DSP library, and triggers the relay module and WS2812B LED rings precisely on each beat. The result is a tightly choreographed display that follows any track you play.
Is the waterproof enclosure enough for an outdoor fountain?
The IP65 enclosure protects the control electronics from splashes and rain. Always position the enclosure away from direct water jets and use appropriate outdoor-rated cables and earthing. The solenoid valves themselves are designed for wet environments.
Can I program my own light patterns and jet sequences?
Absolutely. The WS2812B rings are fully addressable, and the Arduino Mega’s ample I/O lets you design custom animations. The AI companion can help you modify the template code snippet by snippet.
Solenoid valves on fountain nozzles sequence to music BPM. LED ring illuminates each jet in colour.
