555 timer Led Flasher circuit design electronic project

This LED Flasher circuit is based on the 555 timer IC .The LED Flasher circuit diagram is very simple and require few external components . When the circuit is working the red LEDs will flash at a set frequency one by one like at the railway crossing indicator .
The circuit must be powered by a powers supply which can be provide an output voltage between 6 and 12 volts .
