NE555 Timer | Configuring the NE555 Timer in an Astable Configuration

The NE555 timer is one of the most commonly used ICs in the electronics world. It is in the form of DIP 8, meaning that it features 8 pins.

Step 1: View the Video!!!

See the video!

Step 2: Gather Your Materials

The materials list needed for this project is below:

1 x NE555 Timer

1 x 10 nF Non-Polarized Capacitor

1 x Breadboard

1 x Perfboard

1 x LED

1 x 470 K Ohm Resistor

1 x 1 K Ohm Resistor

1 x 220 Ohm Resistor (You can change this value dependant on how bright you want your LED to be)

1 x 1 Microfarad Electrolytic Capacitor

Jumper Cables

Power Source (5V)

Soldering Iron & Soldering Wire

Step 3: Learning the Workings of the IC | the Pinout

The image attached displays the pinout of the IC. This will help you follow the schematic.

Step 4: Circuit Schematic

To make any circuit, the schematic is essential. The circuit for this project is in the picture.

Step 5: Prototype the Circuit

There is a peculiar spectrum here. Some people like to make projects, and leave them on a breadboard. Others don't use a breadboard.

I always find that it is much easier to prototype a circuit first on a breadboard, rather than doing what many people do, start soldering immediately. The reason being is that it is much easier to correct mistakes on a breadboard than on a perfboard.

Simply connect the circuit as it's drawn on the schematic on the breadboard. I won't show how to use a breadboard in this tutorial, but if you don't know how to use one, please leave me a message, and I will write an instructable about it.

Step 6: Finalize the Project & Solder It!

Like I mentioned before, once you're done prototyping, you can now solder it to make it permanent.

Step 7: Final Comments

You're Done!
