/diy/ - Do It Yourself

Beginner in electronics/making stuff. I want to make a halloween prop, a mannequin of michael myers that will play two different sound effects given two different stimuli:

1) intermittently play the "heavy breathing" sound used throughout the film

2) rig up some IR motion sensors so that when someone passes close by, the "sting" (https://www.youtube.com/watch?v=VCjMJbx-BEg - sorry if it's loud) sound plays.


I have a programming background, the logic seems pretty sound. It looks like an arduino would handle my desired use case well. I am curious to know if the arduino uno would be "overkill" for what I want to do. I am also curious about recommendations for speakers. I don't need it all to be especially loud, so I will probably opt for weaker speakers with less power requirements.

Thank you for any and all help.
