Circuits & Schematics Audio - 6

Part 1. Schematic and construction The firmware is completely written in C and can be downloaded from the downloads section below. The firmware is split into 4 parts: ADC Sampling The ADC sampling routine samples the voltage level on RA0 every 50 ...

This project implements a real-time audio spectrum analyser using a PIC18F4550 8-bit microcontroller from Microchip . The spectrum frequency analysis is performed by a highly optimised 16-bit Fast Fourier Transformation (FFT) routine coded entirely ...

Paul Bishop Once again, I decided to put the old travel DVD player's screen to good use by using as an output device for the Arduino. Though the DVD mechanism is broken, the screen allows for standard NTSC composite video input. runs on an ...

Toddy Cangica Introduction I always thought the clapper so cool. For those who are lazy like me, turn on or off the bedroom light without getting out of bed, simple clap your hands is amazing. Thinking about it I projected one for me. Several ...

This simple audio spectrum analyzer is based on PIC32 proto board on PIC32MX360F512L with 320×240px colour LCD ( LVC75Z779 Eval Board ). The analyzer can be connected to unamplified audio source like PC’s sound card, MP3 player and so ...

Szymon Dyja 1. The player allows: playback wav files in stereo format, 22,500Hz freqfency, and 8 bits of resolution, display the song titles, display time of songs, the possibility of stopping (pause) and switch songs, the possibility of change ...

Those of you who imagine that a robot voice generator box would require a whole heap of ICs are mistaken; the ISD2500 ChipCorder family of ICs from Winbond contains almost all the necessary hardware in a single IC to record and playback audio ...

This tool assists you in tuning your string instrument to a given tone. It utilizes the stroboscopic effect to give feedback about the adjustment of your instrument. The two LEDs on the board blink with the frequency that the chosen tone has. When ...

Gabor Toth Description To listen old vinyl LP's in a correct sounding on a sassy with dynamic cartridge you need a circuit, named RIAA corrector. This circuit you can find in old amps, but it isn't embedded in home cinema equipments or amplifiers ...
