This simple VU Meter may be used in variety of
projects. Since real electro magnetic type VU Meters are no longer available
or too expensive, I decided to make this one using LM3914 and 10 LEDs,
which I can use in my other projects.
Here are few important points that this
VU Meter may do:
1. It works on DC Supply from 3V
to 12V (or more)
2. 10 LED group may be one color
or Multi color
3. May be used with AD8307 type
4. Use as a Voltage or Current
meter with proper dividers.
5. Very Low operating current
6. Single Sided PCB: Can be made
at home or on Breadboard
