04/07/2009 Category: Audio, Monitoring, Project

This Audio Spectrum Monitor project use SG12232C graphic LCD to display an audio wave forms in real-time like a digital oscilloscope. It also features a FFT spectrum analysis too. This can also be applied to radio frequency band. As main processor, the project equipped with Microcontroller AVR ATmega8. These are some wave forms that can be displayed, square wave; saw wave and sin(x)/x.
