ADC LED Volume Meter with Arduino Uno - The Learning Circuit

3 Просмотры
The audio signals interpreted by microphones are analog, but the circuits that process those signals are digital. In this build, Karen shows how to use the analog to digital converter in an Arduino Uno to process the audio signals from a stereo microphone kit that she made in a previous episode of The Learning Circuit. The converted digital signals are then used to display the volume on an array of LEDs. Check out the video to see how she does it!
