This is a video tutorial created by Youtuber 68percentwater detailing how to make your own Arduino powered jack o’ lantern with a bunch of moving eyeballs. It is getting a little close to Halloween, but you still have time. This is a nice little weekend project that you can squeeze in and scare the little shits in your neighborhood. It doesn’t look like a lot of work for something so cool all the neighborhood kids will want to leave your house alone and you can keep the candy.
Look in the YouTube comments for a small How-To including sketch code for the Arduino.
I change the eye position for each eye based on a randomly generated number. I grouped the eyes into three groups and made sure I placed them in the pumpkin so each group was spread out, interlacing the three groups so they didn’t all look like they were starting at the same time. while each eye can only move back an forth, I rotated each eye in a way that some were horizontal, some vertical and other somewhere in between. That gave the illusion that they were searching all over and not just scanning back and forth. This was for a contest at my wife’s work. This year she has asked for the pumpkin to shake and vomit. Quite a challenge. I’ll post that one if I’m successful.
