10 led VU Meter using LM3915

Posted on Feb 5, 2014

Circuit diagram is a very simple circuit-level indication, with 10 Led. Used a series of half-wave rectification of precision around IC2 TL071, with a single. LM3915 IC is used to control the led, as an indicator VU Meter. LM3915 can be controlled 10 led. With the switch S1, we can choose an indication from the LED. Level mV into a 60-1st, 25 V. T
