This time I bring an electronic kit for beginners, this is a very cheap and interesting device that displays audio levels into the LEDs just like any audio level bar indicator will do. It is simple and fast to build.
This kit comes with a very simple PCB board to solder the components upon, it has all markings to identify where to put each component, and it uses an LM3915N-1 IC chip to process the signals and display it.
