LED Halloween Pumpkin Display

Halloween is just around the corner, this LED Halloween Pumpkin Display is sure to make a kid looking for some candy stop for a second look. This project by Mike Szczys from Hack a Day used a ton of LEDs and is able to display any message to your Halloween guests.

Thanks Mike.

“The display I built has 70 LEDs. If you individually address each LED you’re going to need 70 pins on your microcontroller. But there’s an easier way. Multiplexing is a method of lighting just a portion of the display at one time. Using a microprocessor you can switch which section is on so quickly that your eye doesn’t ever perceive it being off.”
