10pcs/lot Electronic Brick - Sound Sensor/Microphone Brick

What is an electronic brick?

1. An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components, electronic brick has standardized interfaces, plug and play, simplifying construction of prototype circuit on one’s own. There are many types of electronic bricks, and we provide more than twenty types with different functions including buttons, sensors, Bluetooth modules, etc, whose functions cover from sensor to motor drive, from Ethernet to wireless communication via Bluetooth, and so on. We will continue to add more types to meet the various needs of different projects.

2. Electronic brick of microphone can be connected to the analog I / O port, when speaking to the microphone, the analog value will be changed. A recorder can be made by reading and saving the analog value.
