Stereo Vu meter - second edition

Another of my common requests. My standard vu meter converted too line in, and now stereo. 15 vu meters, and 9 standby patterns. with full build instructions, including upgrade instructions if you have made the old stero vu meter. I have included a push button and bluetooth version ( which includes the android app). please watch the video and take note of the bluetooth warning before building it. code download : Arduino ide: https://ww
