Voice Command Recorder Kit with ESP32 + Servo
Build a Voice-Activated Smart Pill Dispenser with the ESP32-S3 Voice Command Recorder Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you construct a voice-activated medication reminder that listens for a patient’s name and dosage keyword. When detected, the servo rotates a pill compartment and logs the event with precise timestamp. Perfect for assistive technology projects, healthcare hackathons, or CBSE AI innovation challenges.
What You'll Build
You’ll assemble a working voice-controlled pill dispenser from scratch. Speak a wake word followed by a dose command, and the ESP32-S3 activates the SG90 servo to open a compartment while displaying the event on the OLED and logging it to the DS3231 RTC. An active buzzer gives audio feedback for successful dose dispensing, and the entire prototype runs on a reliable 5V supply.
What You'll Learn
- Train and deploy WakeNet keyword spotting on the ESP32-S3 for custom voice triggers
- Interface an INMP441 I2S digital MEMS microphone for high-quality voice capture
- Program servo control and real-time clock logging with the DS3231 RTC module
- Design a complete IoT system integrating display, buzzer, power management, and data logging

Who This Kit Is For
This kit is ideal for CBSE Class 11–12 students building assistive technology prototypes, B.Tech ECE/EEE students working on IoT healthcare projects, and participants of the Smart India Hackathon or ATL Tinkering Lab challenges who need a fully integrated voice-command solution. The intermediate level assumes basic familiarity with Arduino IDE or PlatformIO, but the AI companion fills any knowledge gaps.
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 on the box to access the AI companion trained on this specific project; you can also send a WhatsApp message to our support team for real-time assistance.
Is the medication compartment included in the kit?
The kit provides the servo and a PCB prototype board to mount a small DIY compartment; you can 3D-print, laser-cut, or build a simple box using the enclosure design examples in the printed manual.
Can I customize the wake word and dose keywords?
Yes. The AI companion walks you through modifying the WakeNet model so it recognizes any patient name and dosage command you need, from “Ram, morning dose” to custom labels.
What soldering skill level is required?
Basic soldering experience is helpful. The kit includes a soldering iron, solder wire, and clear connection diagrams printed in the guide. The AI companion can answer specific wiring questions if you’re still learning.
Voice — WakeNet detects patient name and dose keyword. ESP32-S3 rotates servo compartment and logs event with RTC.
