PROJECT DESCRIPTION

This project comprises of circular display of a string of LEDs. Using a high speed motor and some mechanical assembly, LED string mounted on a printed circuit board are duly interfaced to a microcontroller.

An appropriate program while executed drives a pair of single line LEDs in space multiplexing mode. This displays some message and or a clock timing taking advantage of persistence of vision of human eye.

Without the single line of LEDs in space multiplexing mode if one would have to display a message ,number of LEDs as high as 525 would have been used. Here the project uses only 20 LEDs. Thus material count, hardware requirement, brings the overall cost to very affordable price. The synchronizing is be implemented through software.

I found your website on the net, and I found it to be very nice. All components are perfect; I didn’t receive any damaged components.

The project is very interesting. It is really very good experience to me to do this project individually by watching the audio visuals. I got very accurate result also. I hope it is best place to take the engineering projects.
