Schematic Diagram LM3909 IC Color organ electronic project circuit


Posted on Feb 7, 2014

Using LM 3909 LED flasher IC, can be designed various electronic projects. As you can see in this circuit diagram, using the LM3909 LED flasher IC can be designed a very simple color organ. All of three active filters drives the audio spectrum into three bands drive rectifiers and then drive IC2, 3 and 4, flashing the LEDs at 6 Hz. D4, D5 and D
