Gesture Volume Controller Kit with ESP32 + Sensor
ESP32 Gesture Volume Controller Kit – Swipe to Control Volume without Touch
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine adjusting your speaker volume with a simple swipe of your hand, no knobs or remotes needed. This kit lets you build a gesture-controlled audio system using the ESP32-S3 and APDS9960 sensor, mapping up/down swipes to the PAM8403 amplifier's output. Perfect for adding a futuristic touch to your desk or integrating into a smart home prototype.
What You'll Build
A compact touchless volume controller that reads your hand gestures to increase or decrease the volume of a connected speaker. When you swipe up, the volume rises; swipe down, it lowers. The ESP32-S3 processes the gesture data in real time, driving the PAM8403 amplifier that powers the included 3W speaker. You’ll have a fully functional, standalone device that reacts to your movements without any physical contact.
What You'll Learn
- Connect and configure the APDS9960 gesture sensor over I2C with the ESP32-S3
- Write Arduino/C++ code to interpret up, down, left, right swipe events
- Map gesture data to variable volume control using the PAM8403 audio amplifier
- Design a breadboard circuit with proper pull-up resistors and decoupling capacitors for stable operation

Who This Kit Is For
This kit is designed for Indian students who want to go beyond theory—CBSE Class 11-12 electronics enthusiasts, ATL tinkering lab teams, and first-year B.Tech ECE students at colleges like VIT, NIT, or BITS Pilani. It’s also a ready-made prototype for Smart India Hackathon entries or hobby projects that need a futuristic UI element.
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?
Open the AI companion via the QR code on the box for real-time, step-by-step guidance, or send a WhatsApp message for direct human help. We’ll walk you through wiring, code uploads, and troubleshooting until your volume controller works.
Can I modify the code to control other devices with gestures?
Yes, the APDS9960 recognizes up, down, left, right swipes, which can be mapped to any digital or PWM output. You can repurpose the ESP32-S3 to control lights, motors, or send commands over Wi-Fi for IoT projects.
Does the kit include a power supply, or do I need to buy one separately?
The kit includes a Micro USB cable to power the ESP32-S3 from any standard USB adapter or power bank. The amplifier and speaker run off the board’s 5V output. No separate supply needed.
Do I need prior experience with Arduino or ESP32 to build this?
No. The AI companion provides a complete beginner’s walkthrough with wiring diagrams and pre-written code. You’ll learn by doing, with explanations for every line and component.
APDS9960 gesture sensor detects swipe direction. ESP32-S3 maps gestures to volume up/down on PAM8403 amp.
