Introduction
We started as a hobby don`t know when it became a passion and we come with this startup. Our aim is to use a microprocessor to control a row of LEDs to display some images and function. The leds turn on and off, one after another, very rapidly. Due to the slow response of the human eye, we get the impression that the lights are on all together and we can read the display.Scanning in this clock is mechanically. The leds are turned on and off at very precise times and places. Several sensors including infrared proximity sensors are used to detect the completion of onerevolution.
How this clock works
The basic principle used is the persistence of vision. As the LEDs rotate at a high speed they can be controlled with the help of a micro-controller So as to glow them in such a combination that a floating display is formed. A motor spins the "propeller", And a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing too Simulate an array of LEDs. It is an illusion, but it works nicely.
