Simple Audio VU Meter Kit (iPod Output and a speaker out plug)
This is a fun kit that utilizes two 3914 chips to display the dB of your music on a 20 led bar-graph display. This kit is very adaptable and can be incorporated into another project, for example making a tower of lights, then hooking the circuit up to your tower and then you have a really cool LED dB meter tower in your living room or tech cave. The speakers that are connected to the audio out on the circuit should be powered or you will take away a lot of signal from your led VU meter resulting in a dull display that only flickers 3 or 4 LEDs on and off.
