Voice Recorder and Playback Module Kit with Arduino Uno
Record and Play Voice Clips at Room Volume with the Arduino Uno Voice 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.
Transform a simple button press into a custom voice message player that fills a room. This kit lets you build a functional voice recorder that can be used as a talking doorbell, a voice diary, or an audio greeting card — all controlled by an Arduino Uno. With dual ISD1820 modules and a PAM8403 amplifier, you learn how recording chips, microcontrollers, and power audio stages work together.
What You'll Build
You’ll assemble a standalone voice recorder that captures up to 10 seconds of audio per clip and plays it back through a 3W speaker at room-filling volume. Two ISD1820 modules let you record and toggle between multiple messages using tactile buttons, giving you direct control over recording, playback, and loop modes. The breadboard layout and wiring will be fully documented, so you can later house the circuit in a custom enclosure.
What You'll Learn
- Interface ISD1820 voice recording modules with Arduino Uno for playback control
- Use a PAM8403 amplifier to drive an 8Ω speaker without distortion
- Program button debouncing and state logic to manage record/play sequences
- Design low-voltage audio circuits on a breadboard, including filtering and power decoupling

Who This Kit Is For
This kit is ideal for CBSE Class 11–12 students building a working audio electronics project for their practicals or science exhibition. B.Tech ECE/EEE first-year students can use it as a mini‑project to understand microcontroller-based audio recording and amplification. It also fits perfectly into ATL Tinkering Labs and Smart India Hackathon prototypes that need a voice feedback module.
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 to open the AI companion trained on this kit. It walks you through wiring and code, and you can reach us on WhatsApp for direct troubleshooting.
Can I record multiple audio messages and play them separately?
Yes. The two ISD1820 modules each hold an independent voice clip, and the Arduino program lets you trigger them individually with different buttons, so you can alternate between messages.
How long can each voice recording be?
Each ISD1820 records up to 10 seconds of audio. The PAM8403 amplifies playback loud enough to fill a room, and you can chain modules for longer messages if needed.
Can I connect a larger speaker for louder output?
The PAM8403 is rated for 3W into 8Ω. The included speaker already delivers room‑filling volume. You can connect a slightly higher‑wattage 8Ω speaker, but we recommend sticking to the supplied one for safe, distortion‑free sound.
ISD1820 records and plays back voice clips on button press. Paired with PAM8403 for room-fill volume.
