PROJECT DESCRIPTION

This project is intended to design musical-tone-based dancing LEDs  those  illuminate in synchronization  with the music tone played or speech  .

This system uses a microphone through which the musical sound is picked up and amplified. Then this amplified signal triggers a sequence of LEDs through an intermediate circuit. Hence,  flashing of  LEDs  happens when an audio music  constantly changes its beat. As a result a rhythmic sequence of  changing LEDs appear with the changing beat of the music.   

In future the project can be enhanced by using TRIACs and Opto-Isolators to use high power lamps in place of LEDs.

Q & A
Q:  What is rhythm following flash lights?
A:  Rhythm following flash lights is a series of LED lights operating according to the rhythm or pitch of the audio or song.
Q:  How is the sound signal picked up?
A:  A condenser microphone is used to pick up the sound signal
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.

I come to know about Edgefx through Internet. I used embedded projects as a keyword in the Google.
I decided to buy a kit from Edgefx by having a look on the website it’s attractive. I like the complete kit.
I purchased through online.
