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.

I have seen a product can do it,like picture .use OTP voice chip or voice module and add a motion sensor ,but it used for pop display ,voice prompt ,what kind of project do you do?
I think you should buy a pcs voice module or voice chip and motion sensor first.

Try a simple Thermin trust me it can scream and make UFO sounds.

Thank you so much! Can you program the Thermin to record your own scream? Is the scream more of a typical canned scream, like one you would hear in horror movies or in halloween music?

A Thermin is a sound generator for two hands.

One hand controls Volume and the other hand controls a Frequency.

Using both hands you can create amazing sounds with a little practice.

To make a musical tune takes a lot more practice.

I hope it is clear your hands never touch the Thermin which
is operated by sensing where your hands are in relation to
the device.

an arduino would require a lot of initial time learning if all you want to do is having a sensor activate a sound. You should look for "off-the-shelf" solutions (Even as non-techie as a doll that will replay a recording when it sees you - if such a toy exists :-) A little more technical solutions could be a sensor-module and a replay-module, that with perhaps only a few minor parts can be directly connected to eachother without all that arduino programming nonsense ;-)

More of a suggestion on an alternative solution than an actual answer I suppose.

(If you goal however is to do more with arduinos in the future, and you have the time, then that route makes more sense - but for a one-off project it is not really worth it imho)
