Introduction: LED Bulb for Arduino

Hi! In this Instructable, I will be showing you how to create a LED bulb that you can connect to an Arduino, or a battery. You can incorporate this into your existing projects!

You will need:

A Straw

Some Wire


An Old Light Bulb

Step 1: How Out the Original Bulb

For instructions on hollowing out the bulb, follow this Instructable: Credits Electrospark

Step 2: Set Up the LED

For this step you will need a straw and a wire. Cut the wire a bit longer than the straw and thread through the straw. Connect the wire to the LED. It should look like the photo.

Step 3: Poke the LED in the Bulb

Cut a piece of styrofoam to fit in the bottom of the bulb. Poke a hole in the middle enough for the straw to fit through. Then push the straw in the hole.

Step 4: Add to Your Existing Project

This makes a good indicator light for your existing project. Enjoy! (Sorry for the bad quality photos I'll try to update them!)
