In this paper, the authors explain the project which is a special kind of circular LED display. With the help some mechanical assembly, LED count, hardware requirement, and hence overall cost is cut to very affordable price. Also, maintenance and repairing of the display is so easy, that anyone having a little electronics knowledge can take care of this. All the synchronizing can be implemented through software. First of its kind, made using the 20-pin 8051 series microcontroller, this paper use the principle of Space Multiplexing. This propeller display is mechanically scanned and displays the characters in digital format.
