Direction Indicator

Direction indicator is very interesting as well as very useful project in any ceremony, party etc. to indicate places like bathroom. The alternate glowing LEDs in direction indicator make this project more attractive.

Circuit description of direction indicator

The logic of direction indicator is very simple and is designed and fabricated around CMOS HEX inverter buffer CD4049 containing six independent inverter (a-f) . For effective use of this project all LED must be of RED color.
