ESP32 Servo Orchestra Kit - Beat-Synced 8-Servo Dance Project
ESP32 Servo Orchestra Kit - Build an 8-Servo Ensemble That Dances to Music
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 a desk into a stage where eight servo motors move in perfect sync with any beat - pop, EDM, Carnatic rhythms. This kit lets you choreograph physical motion driven by live sound captured through a MAX9814 electret microphone amplifier, processed on a dual-core ESP32. Build a servo orchestra, a kinetic art installation, or a tangible music visualizer that responds instantly to claps, instruments, and bass drops.
What You'll Build
You'll assemble a standalone 8-servo array capable of independent, beat-timed motion. Each SG90 connects directly to an ESP32 LEDC PWM channel, letting you run fluid, concurrent movements without jitter. The MAX9814 module captures real-time audio envelopes, and your firmware extracts onset peaks to trigger custom dance sequences. The final build mounts cleanly on two PCB prototype boards with onboard bulk decoupling capacitors, powered by a 5V 5A supply so multiple servos never starve.
What You'll Learn
- Configuring ESP32's LEDC peripheral for hardware PWM on 8 channels with 16-bit resolution
- Real-time envelope detection and onset triggering from MAX9814 amplified audio
- Choreographing servo movement patterns with non-blocking state machines
- Power distribution design: bulk and decoupling capacitance for multi-servo stability

Who This Kit Is For
This kit is built for engineering undergraduates - B.Tech ECE, EEE, or E&I - who want a challenging semester project or a Smart India Hackathon prototype. It also fits advanced hobbyists from IIT, NIT, VIT, BITS, and ATL Tinkering Lab mentors guiding college-bound students. If you've already worked with Arduino and servos and are ready for ESP32's dual-core and precision LEDC control, you'll find the right depth here.
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.
What if I get stuck during the build?
Scan the QR code for the AI companion, or WhatsApp us directly. We'll debug your firmware, wiring, or power delivery - same day.
Can I choreograph my own servo sequences?
Absolutely. The AI companion includes reference code with an array of pre-defined movements and guidance to design your own beat-to-motion mappings.
Does it work with any music genre?
Yes. The envelope detection responds to attack transients across genres - from tabla bols to EDM kicks. You can tweak gain and threshold in the firmware for best results.
Do I need advanced soldering skills?
You'll solder headers, capacitors, and power rails onto prototype boards. The AI companion walks you through each joint, making it a strong skill-builder even if you're new to iron work.
