MIC sensor is a microphone-based sound sensor for ambient sound detection. It acts like a microphone, which is capable of detecting sound intensity and converting sound energy into analog electrical signal. These sensors are more commonly seen in recoder, sound-controlled lighting system, etc. <br/> It works well with maincontrollers like Arduino, micro:bit, etc., and also supports graphical programming platforms such as MakeCode, and Mind+.
1. Example Code for micro:bit-Smart Streetlight
At night, when people walk under the streetlight, the sound sensor detects the sound and the LED lights up for a while and then turns off.
2. Example Code for micro:bit-Light and Sound Interactive Cake
Make a birthday cake. When playing the birthday song and the sound sensor detects the sound, and the colorful LED strip lights up.
3. Example Code for micro:bit-Noise Detector
The article offers a complete guide on building a micro:bit-based noise detector, detailing hardware setup, wiring diagrams, and providing sample code for graphical programming platforms MakeCode and Mind+. It includes visual aids and demonstrates the end result through a video demo, making it accessible for beginners interested in DIY electronics projects.
