Connect pin 8 with the positive end of battery.Connect pin 7 with the positive end of battery using 1kΩ resistor.Connect pin 6 with pin 7 using a 470kΩ resistor.Connect pin 4 with the positive end of battery.Negative lead of LED needs to be connected with the ground. Connect the pin 3 which is the output pin with the positive lead of LED using 1kΩ resistor.Also connect the pin 2 with pin 6 of the 555 timer IC.Connect the negative lead of the capacitor with the ground of battery. The longer lead of a polarized capacitor is the positive and the shorter one is negative. Connect pin 2 to the positive end of capacitor.You can see the pin structure of 555 timer IC in the pin diagram shown below. Connect pin 1 of 555 timer IC to the ground.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.
