Makeblock - Me Sound Sensor

Based on a microphone, the Me Sound Sensor can be used to detect the ambient sound intensity. Its main component is LM2904 low-power amplifier. The module can be used to build some interactive projects, such as the voice operated switch, and the dance-following robot. Its black ID means that it has an analog port and should be connected to the port with black ID on Makeblock Orion.

Functional characteristics

• Brightness of onboard LED indicates the intensity of sound
