Random Flasher for 8 LEDs Project This project flashes eight LEDs in an apparently random manner. It uses a 4026 combined counter and display driver IC which is designed for driving 7-segment LED displays. The sequence is not really random because seven of the LEDs would normally be the display segments, the eighth LED is driven by an output that is normally used for driving further counters. The table below shows the sequence for the LEDs. You can use less than eight LEDs if you wish and the table may help you decide which ones to use for your ....etc

This Project is very simple and when completed, causes a light-emitting diode (LED) to flash or pulse alternately on and off at a very slow rate, that is, at a low frequency. It could be used as a dummy car alarm indicator. You sometimes see these tiny pulsating lights in expensive cars protected by sophisticated car security systems, warning you that the car alarm is armed and ready.
For this design, the LED flashes on for a brief period and stays off for a relatively longer period. Because additional current is consumed from the battery ever ....etc

I feel as though there are many individuals on this site who haven't had the opportunity to see what our customers are doing with our products . I know browsing through thread after thread to see results can be daunting, so I've gone ahead and collected photos from many various grow demonstrations that are either completed, near completion, or in progress to show you that the future of lighting technology is here!

SUPER BRIGHT LED FLASHER



This is a novel flasher circuit using a single driver transistor that takes
its flash-rate from a flashing LED. The flasher in the photo is 3mm. An
ordinary LED will not work. The flash rate cannot be altered by the
brightness of the high-bright white LED can be adjusted by altering the
1k resistor across the 100u electrolytic to 4k7 or 10k. The 1k resistor
discharges the 100u so that when the transistor turns on, the charging
current into the 100u illuminat ....etc

PROJECT REPORT ON MULTICOLOUR LED DISPLAY



ABSTRACT

LED's are a fantastic way to illuminate any kind of sign, be it lettering or panels.
LED Dot-Matrix Displays are a common sight nowadays on streets, malls,
buildings, parks and other public places. It is a way of visual information where
large LCD and other display become too much expensive. The commonly seen
displays are single coloured or having 2 or 3 colours .But here multicoloured LED
display is being introduced .This project provides an effici ....etc
