Halloween isn’t over yet, there is still time to make something cool for Halloween. Here’s a few to inspire you.
First up is Halloween Prank. While not a completed project, this is a good base for Arduino powered scare tactics! The build uses an Arduino, an Ultrasonic distance sensor, and a servo. By detecting ‘someone coming to your door’ possibly, the servo is triggered. In Jacob’s build the plan is to drop a bunch of spiders on people walking up. That sounds like fun. You could also make it actuate something to jump out at your unsuspecting victims.
Source code for Halloween Prank is available here on GitHub. There are more pictures and a test video on Jacob’s site.
