Motion sensor that will play a sound? Answered
I need to create something for a class project. Basically I need something that will "scream" (play a pre-recorded sound) whenever someone gets close to it. I have almost no experience with making things like these. I imagine I will need a motion sensor of some kind and a set of speakers? What else would I need? What are some next steps? My friend told me something called an arduino might help me.
