The project consists of Spinning LED display using RF which displays the messages send by the user at the handheld device. if there are no inputs from the user for the system, the message that is programmed in the microcontroller will be displayed continuously. The circuit needs to be mounted on a mechanical structure that rotates at high speed. The display consists of 7 LEDs only in a vertical row. By moving them fast enough, message can be displayed which appears to be generated by a 7*n matrix of LEDs and not a single column of LEDs, where n is the no. of columns of the display matrix. This illusion is based on inertia of human eye or in other terms PERSISTANCE OF VISION. It consists of motor and seven LEDs that are arranged in a vertical line. The motor spins at a constant rate such that the LEDs rotate around a centre pivot point. As the LEDs spin around they light up sequentially such that they will display the message. The motor spinning fast enough that the human eye will perceive all of the display is on at once, and the viewer will be able to read the message completely. If LED formed message will periodically and frequently enough flash, they will appear solid and steady. A microcontroller is used to keep the message and blink the LEDs in an appropriate pattern. It has to be programmed so that it will both keep message and also send the appropriate signals to the LEDs to light them in the correct sequence.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
