Single IC stereo LED VU METER LM3914 or LM3915 or LM3916

I show you how to make a Single IC stereo LED VU METER LM3914 or LM3915 or LM3916.
This IC is specifically design for voltage level indicators, so it is widely used as a peak level indicator, engine speed indicator on motorcycles and cars (RPM indicator), etc.

The both Transistors (C1815) in this circuit is works alternately to cut off the signal input "Left and Right" alternately depending the frequency on transformer or electric sources at your home.
This circuit need input signal at least 2.5 Watt.

You can do it yourself even you don't have an electronic skills yet, just watch carefully conscientiously and use Play & Pause button to catch something for the details.

Attention!
Especially in the transformer you must be careful, because the primary side will be connected directly to the power source at your home.
