Sprektrum analizer + watch
The general hobby of modding has not bypassed and me. Two lights-emitting diode matrixes 5*8 was completely becoming in a five-inch compartment of a computer – that I had seen decided to make it on basis of spectrums’.
This is idea of the device: 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 a light-emitting diode matrix. I have looking for information on decomposition of a sound and conclude, to make it with the help of special library for processing a sound bass.dll with distribution what include set of examples in different programming languages of high level.The microcontroller ATMEL AT90S2313 is the heart of device, if the program to alternate it is possible to use and ATTINY2313.
