LED Flasher | Blinking LED Circuit using IC 555 Timer- By Manmohan Pal

LED Flasher
Blinking LED Circuit Using a 555 Timer IC
Circuit Components
1. 555 timer IC
2. LED (any colour)
3. 9 V battery
4. 10KΩ Resistor - 2
5. 330Ω Resistor - 1
6. 100µF 25 v Capacitor
7. Bread Board
8. Connecting wires
Circuit Diagram
The following circuit design explains the design of the blinking LED with the 555 timer IC. Here in this configuration, the 555 timer IC has connected in an Astable mode of 555 timer operation.

*Collect all the required components and place the 555 timer IC on the breadboard.
*Connect pin 1 of a 555 timer IC to the ground. You can find the pin structure of a 555 timer IC in the circuit diagram shown above.
*The longer leg of a polarized capacitor is the positive and the shorter lead is negative. Connect pin 2 to the positive end of a capacitor. Connect the negative lead of the capacitor to the ground of the battery.
*Now short the pin 2 to pin 6 of the 555 timer IC.
*Connect the output pin 3 with the positive lead of the LED using a 1kΩ resistor. The negative lead of LED needs to be connected with the ground.
*Connect pin 4 to the positive end of the battery.
Pin 5 does not connect to anything.
*Connect pin 6 to pin 7 using a 470kΩ resistor.
*Connect pin 7 to the positive end of the battery using a 1kΩ resistor.
*Connect pin 8 to the positive end of the battery
Finally, connect the battery leads with the breadboard to start the power supply in the circuit.

Very nice. Wonderful.

[@ManmohanPal]

Welcome, please find more LED projects in my play list

[@ManmohanPal]

Keep like comments and sharing among the friends and relatives

[@myelectrojj]

*Nice video* 👌😋

[@ManmohanPal]

Thanks

[@sid00143]

Y did u connect led with pin 4. Its not ground.

[@ManmohanPal]

pin 4 is connected to pin 8 which is connected to + ve supply the other - ve end of LED is connected to pin 3 which is out put pin of IC

[@akankshaprasad6857]

Can i use 10uf instead of 100uf capacitor?

[@ManmohanPal]

Blink time will increase

[@ManjitSingh-ec6ky]

Nice video

[@rakeshjangid1818]

I wants that LED blink in every 1 minute..Do its possible and how..?

[@chaithanyanayak8355]

what is the specification of the LED used?

[@ManmohanPal]

4 mm 3 volt

[@VikasDounde]

Hi Sir reverse and forward DC motor automatically work circuit diagram

[@anjali31_7]

What is value of Potentiometer??

[@dineshsoni1721]

1 second off 1 second on after 5 second total off is possible

[@m.relectronics7223]

switch se on kanaheto kaha lagaye

[@ManmohanPal]

Battery ke positive terminal pe

[@m.relectronics7223]

Dabanepe 12section on rahe badme off teba wala batan laganahe

[@raghilstories1325]

I will chat with you soon

[@m.relectronics7223]

12second on and 60second off 555 ka timer banega

[@m.relectronics7223]

Please reply

[@ManmohanPal]

Bnjayega par aap ko ye kha use krna h ye bataiye

[@ManmohanPal]

Same circuit ka use krna h to R1 R2 aur Capecitor ki valie change kr k bna skte h
