Stereo VU Meter Kit
VU Meter seems to be the ultimate audio visualizer for any audio systems. Even though there are many options available, a simple, classic LED bar display are rather hard to find. This VU meter kit features switchable bar-graph / dot display and waterfall peak hold display that resembles the classic LED VU meter from the late 70's. Add this to your audio system for that extra listening enjoyment. The main circuit and the LED board are separate, to give you maximum options for installing into the enclosure of your choice. They are connected by only 8 pins, so extending is easy, too. Firmware has some useful options like Left/Right channel swap, scan direction reverse (the meter runs right to left). Firmware source code is open, so that you can tweak the functions to your liking as you desire. Please note that the power supply for this VU meter is DC 5V. Supply voltage higher than 5.5V can damage the components. Please only use regulated power supply. The most convenient and economical op
