Halloween is near, and I've had a lot of requests for another Arduino Halloween Project. If you didn't get a chance to look at my Animated Skull project, definitely check that one out too! For this activity, we're going to be making Twitching Eyeball Pumpkins. (Shoutout to 68percentwater for this idea!) The goal is to scare people with this monster-like decor! This project is really fun to do with the family or independently for fun. Set aside a half-day to carve, assemble, wire, and code your very own Twitching Eyeball Pumpkin.

Carve your Pumpkin

I highly recommend using a "funkin" or foam, synthetic pumpkin for this project. Funkins can be carved like regular pumpkins and will avoid all of the "guts" (and glory) that could damage your Arduino and Electronics. If you do decide to get a real pumpkin, you'll have to place your Arduino and wiring into …

  1. How long would the batteries last in a typical set-up. I’ve seen this project elsewhere and one of the big problems expressed was the amount of current that the servos draw. Is this an issue?

    1. Liz Miller

      Jason, good point. Yes, the batteries will drain if you’re planning to keep it running. Depending on what battery you use this could be 20 hours to a day. Arduinos are constantly drawing current ~15mA a cycle even if they’re doing nothing. I recommend keeping it plugged into a wall adapter for the time you’re planning on having it on display.

  2. Frans Geeraert

    Adding sound would be nice!

    1. Yes, definitely! Pretty easy to do, as well. All you’d need is a speaker & an SD card with whatever song you’d like! Nice idea!
