How do you make a simple flashing LED circuit?

Hello Guys , In this post we learn how to make simple flashing led circuit in easy way and cheap in price.

Let Start it:-

*Parts Required

555 Timer IC
1uF Capacitor
470k Ohm Resistor
1k Ohm Resistors (2)
9v Battery

*Schematics & Diagrams

-do all the connection according to this diagram.

*Steps how to make it

Collect all the required components and get ready! Place the 555 timer IC on breadboard as per shown in the breadboard setup image given above.
Connect pin 1 of 555 timer IC to the ground. You can see the pin structure of 555 timer IC in the pin diagram shown below.
Connect pin 2 to the positive end of capacitor. The longer lead of a polarized capacitor is the positive and the shorter one is negative. Connect the negative lead of the capacitor with the ground of battery.
Also connect the pin 2 with pin 6 of the 555 timer IC.
Connect the pin 3 which is the output pin with the positive lead of LED using 1kΩ resistor. Negative lead of LED needs to be connected with the ground.
Connect pin 4 with the positive end of battery.
Pin 5 doesn’t connect with anything.
Connect pin 6 with pin 7 using a 470kΩ resistor.
Connect pin 7 with the positive end of battery using 1kΩ resistor.
Connect pin 8 with the positive end of battery.
Finally connect the battery leads with the breadboard to start the power supply in the circuit.

*Preview

-Enjoy
