ContentsObjectiveSpeak toward MIC, the lamp will change along with the sound rhythm. principle
MIC sensor can turn sound signal to electricity signal. It can detect sound volume but can't detect certain sound.
Detect sound volume via MIC sensor and the system will judge which color range the sound belongs to. At the same, comparing with the pre-set trigger value and choosing to open or close light change, therefore, to control color change of the lamp. Equipment
