ISD1820 Voice Recording & Playback Module with Speaker
Short Description (SEO Meta):
Record and play 10s of audio with the ISD1820 Voice Module. Includes speaker & mic. Perfect for Arduino projects, toys, and DIY sound alarms.
Description:
The ISD1820 Voice Recording Module is the easiest way to add high-quality, natural-sounding audio to your electronics projects. Whether you are a student building a talking robot or a hobbyist creating a custom doorbell, this module provides a complete "plug-and-play" solution. It features an on-board microphone for recording and a powerful internal amplifier that can drive the included 8-ohm speaker directly—no extra circuits needed!
The best part? Your recordings are stored in "non-volatile" memory, which means the module remembers your voice even after you turn the power off. You can control it manually using the on-board buttons or connect it to an Arduino, ESP32, or PIC microcontroller for automated voice alerts.
Features:
Simple Push-Button Control: Dedicated buttons for Record (REC), Edge-triggered Play (PLAYE), and Level-triggered Play (PLAYL).
Built-in Microphone: No need for external audio input; record directly onto the board.
Direct Speaker Drive: Includes an 8Ω 0.5W speaker that connects directly to the on-board headers.
Microcontroller Compatible: Easy 3-pin interface to trigger recording and playback via code.
Non-Volatile Storage: Retains recorded audio for up to 100 years without power.
Adjustable Duration: Default 10-second recording can be adjusted between 8–20 seconds by changing a single resistor.
Applications:
Talking Toys: Add custom voices or sound effects to plushies and action figures.
Security Alarms: Play a pre-recorded voice warning when a sensor is triggered.
Educational Projects: Create interactive science fair displays with audio instructions.
Smart Doorbell: Record a custom greeting for visitors.
Annunciators: Use in vending machines or lift systems to announce status.
