Vu-Meter 20 LED DIY Dot/Bar mode with LM3915 and LM386

This is the "Perfect Vu-Meter" The best I've ever made. A Vu-Meter with 20 LEDs, two LM3915 and an integrated LM386 amplifier, it is also possible to connect a stereo signal to the input, and a graphical view with dot or bar mode.. This circuit is equipped with an audio transformer (TTC-167) that allows to separate the amplification circuit of the signal from the measurement one.. LM7809 takes care to keep the 9V voltage stable throughout the circuit. ► Features: 20 LEDs with *standard color scale LM3915 as LEDs driver LM386 as Amplifier 167-TTC Audio Signal Transformer Stereo Input (Low Level from RCA) Adjustable Gain LED Test button DOT & BAR mode 230V Power Supply *The standard color scale for a Vu-Meter is: 10 Green LEDs, 6 Yellow LEDs and 4 Red LEDs.
