LED Bulb for Arduino


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!)

    Thanks for crediting me with the link to my instructable! :)

    It's strange, I am making an instructable on how to make a Steampunk LED lamp out of old light bulbs and I actually put LED's in the light bulbs the same way than you without knowing it!

    fog the glass of the bulb, and although dimmer, it would look like the whole bulb was lit up :)

    I love the little LED inside the big bulb! :)
