Digital Clock Featured Spectrum Analyzer

Overview

The project is a computer controller spectrum analyzer and clock which was constructed using two light emitting diode on 5x2 matrices.

Explanation

The heart of the device is the Atmel AT90S2313 microcontroller where data from a serial port is accepted by the controllers and the additional decoder 74145 is deduced in a spectrum on the LED screen that are collected from two matrices with the help of conclusions of port B.  the 2 operating modes are columns and points.

During the process, the computer program should allocate a spectrum of a sound signal and through a serial port to transfer the data to the microcontroller which in a dynamic mode serves an LED matrix. The device was constructed on two PCBs where the LED matrices were established in the first and the second contains other elements. An unused plastic of 5-inch insert is cut to produce the decorative overlay.

The managing program from the part of a computer is written on VISUAL BASIC while the program of the microcontroller was written in BASCOM-AVR. The program can be altered from its library for processing a sound bass.dll and some fragments can be added to it.
