In this article, you will learn about led flashers. Led flasher continuously blinking in nanoseconds. In my designed circuit I used BC547BG Transistor for switching. When the transistor switch is open led will be off state and when the transistor switch is close led will be on the state. My designed circuit has contained only 5 different color's LEDs. You can add more than 5 LEDs to the circuit Here is the circuit. Input is 9-volt dc and circuit contain 5 Resistor 1k, 5 Resistor 22k, 5 Transistor BC547, 6 22uf Cap Capacitor, Connect all positive sides of LEDs with a positive side of the supply. The circuit has positive power but on the negative side, the transistor is connected for switching. How make a circuit? First, open Multisim and then place all LEDs like this Then place all the transistors like this. Then place the 22k ohm resistor and 22uf Cap capacitor. Then connect all the components like this. The place the 9 volt supply Now circuit the is complete. Run the...
