This Sunday was a real hectic and productive one. I finally got a pending idea to work with a Freeduino board I acquired from the KHOJ workshop. Watch the video and continue reading after the jump.



The assembly uses a condenser mic, a single transistor amplifier, a Freeduino Lite board, a 9V battery and 5 LEDs. As you can see in the video, the lights turn on according to the intensity of the music/speech. The fun part is that it switches to a soothing ambient light mode when the music is turned down.
I got a sort-of-okay code working here. It is not fully optimized but it works.

A happy new year to all!
Whats a better way to start the year than playing with the Arduino board!
Thanks to Aparna and Maitreyee, I visited the electronic hobbyists' market in Chandni Chowk to buy some basic stuff (LEDs, breadboard, wires, soldering iron etc).
I started off with basic computer-board communication exercises. This is one of the things I tried – A 6 series LED chaser.
