This project will show you how to make an awesome PIC controlled pumpkin that flashes different LED's to the tune of the Adams family at the same time as it plays the Adams family theme song through a speaker.

This video is of the LED lights going off outside of the pumpkin.


Sorry, I couldn't get my camera to pick up the light coming out of the pumpkin well enough to be worth including the video of this really working.

Step 2: Materials

Materials:

- Pumpkin!

- Super Bright LED's- I used regular LED's, and I think it would look a lot better with the super bright type of LED's

- Some kind of Micro-controller board - I used the Parallax Basic Stamp two because that was what I had, but I'm sure the Make Controller or some other type of controller could be used as well.

Nails- These will be used to hold the Micro-controller board onto the side of the pumpkin, you might not need these depending on how your controller can be mounted

Optional:

Computer Speaker- this will serve as an amplifier for the small speaker that comes with the Micro Controller

Tools:

Knives


Step 3: Carve Your Pumpkin!

I personally like to make my pumpkin scary, but this is the part where you get to decide what you do. The only thing that you will have to worry about is whether your LED's will be bright enough to show through your design. To make sure your LED's will shine through, don't make any really big holes in your pumpkin where light can escape. For some great pumpkin design ideas try this site
