Flashing Light Circuit Using NE 555 IC

Introduction:

                          This Project is Flashing Light or Blinking Light Circuit. This Circuit is a Very Basic and Easy Circuit for the Beginner Students. This Timer IC is Very Easy to Understand and Use for the Projects. This Circuit was Made with the NE 555 IC. For Know More About this Project, Read More.

Connection:

                 This Circuit is Made with NE 555 Timer IC. This IC Control the Time Variations by Changing the Capacitor and Resistor. In this IC, 1st Pin of the IC connected to the Ground. Then the 4th and 8th Pin of the IC is connected to the Positive of the Power Supply.1K Resistor, 10K Variable Resistor, and 100μF Capacitor is Connected Seriously Between +ve and -ve of the Power Supply. 7th Pin of the IC is Between 1KΩ Resistor and 10KΩ Variable Resistor. The 6th and 2nd Pin of the IC Connected in the +ve of the 100μF Capacitor. Then Finally, the Output Pin is the 3rd Pin of the IC connected to the LED’s +ve. And Ground is Connected Seriously with the 220Ω Resistor to the LED’s -ve. Thus the Circuit Connections Fulfilled.

Working:

                 The Timer IC is Control the Output Object By the Time Variation. Similarly that, In this Circuit. 1K Resistor, 10K Variable Resistor, and 100μF Capacitor is the Time Variation Section. When the 100μF Capacitor is Charged Through the 1K Resistor and 10K Variable Resistor, Thus the Current Flowing Through the 3rd-Pin of the IC to the LED. This Process is Repeatedly, Again and Again, The LED was Continuously Blinking on the Particular Time Duration. By Adjusting the Variable Resistor, Thus The LED Blinking in Particular Time Duration Proportional to the Variations of the Variable Resistor.
