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.
