Circuit Diagram
Circuit Explanation
This circuit is a simple and easy-to-use device that can record and play back voice or audio messages. It uses a special chip called the Win bond’s ISD1616 IC (SMD) IC, a small, single-chip system designed to work in many electronic products. The messages are saved directly onto the memory without any compression, so you get high-quality, solid-state audio that sounds great.
The circuit is easy to operate and lets you choose the length of your message, from 10 to 20 seconds, depending on the sampling rates. You can adjust the sampling rates using the onboard potentiometer, which gives you greater flexibility regarding recording time versus quality. You can record and play back messages using the onboard buttons.
The circuit runs on 5V DC and uses very little power in standby mode, which helps to save energy. When you finish recording or playing back a message, the circuit automatically goes into standby mode to save power.
Applications
The simple voice recorder and playback circuit is a versatile device we can use in many applications. Examples of applications include:
- Interactive games
- Sound and light shows
- Educational toys
- Robots
- Elevators
- Alarms
- Audio guides
- Home appliances
