Digital clock circuit with alarm by LM8560

These two circuits make a LED fade on and off. The first circuit charges a 100u and the transistor amplifies the current entering the 100u and delivers 100 times this value to the LED via the collector-emitter pins. The circuit needs 9v for operation since pin 2 of the 555 detects 2/3Vcc before changing the state of the output so we only have a maximum of 5.5v via a 220R resistor to illuminate

Of course, the simplest LED flasher is simply to use a flashing LED. The problem with that approach is you have no control over the flash rate, but it does have its use for eye catching displays for selling stuff. The circuits below give you that control, plus they can flash two LEDs alternately.

7 Segment Display Counter Circuit using IC 555 Timer IC

The current consumption in the “sleep mode” is around 4mA, in this mode the LED display remains switched OFF but the clock keeps the timing updated correctly so that when the displays are switched ON again, it provides the current timings accurately.

LED Scrolling Display Board Circuit Using AVR Microcontroller

The working of Rotating LED Display is very interesting and it can be used for decoration purpose, where you can make beautiful designs and graphics using this amazing project. This display can also be used in public places like railway/ bus station and airport as a sign board, as it is very cost effective to build. Proper maintenance is necessary for the gear motor and rotating assembly.
