ES - Digital VU Meter (Arduino - .Net)
This project is for an Arduino UNO and provides a VU Meter display (with LEDs). The Arduino listens for data on the serial port and visualizes the Volume peaks send by the host over serial. On the host, the application VUMeter.exe runs in the background and reads the volume peaks from a soundcard and sends this data to the Arduino.
This project is Open Source. The source code and schematics including a PCB design can be found below.
