PROJECT DESCRIPTION

This project comprises of a circular display with a string of LEDs in propeller mode. Using high speed motor and some mechanical assembly, the LED string mounted on a printed circuit board duly interfaced to a microcontroller displays the message virtually.

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

Without a single line of LEDs in space multiplexing mode if one had to displaya message,the number of LEDs as high as 525 would have to be used. In this project there are only 10 X 2 set of LEDs. Thus, material count, hardware requirement, brings overall cost to very affordable price for a magnificent display. Synchronizing is implemented through software.

Q & A
Q:  What is the motor rating used?
A:  The motor rating used is 12V, 10RPM
Q:  What is wireless power transfer?
A:  Wireless power transfer is transferring of power wirelessly, using mutual induction of 2 coils in HF.
Q:  What is the difference between HF transformer and general transformer?
A:  High frequency generation in HF transformer has got fewer losses compared to iron core transformer
Q:  What is propeller display?
A:  Propeller display is mechanically operated rotating set of LEDs to virtually display characters / a message in digital format
