LM3909 IC bassed Color organ electronic project
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 .
This circuit is not complicated , it use just some common active audio filters for filtering audio signals and a part formed by a LM3909 IC .
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 D6 should be three different colors for best effect .
In the table bellow you can see all electronic parts required by this color organ project .
