I have 2 ideas a motion sensing alarm and fake sound maker. id like to make both connect to my phone through an app ill make on codex. Im really good with ai coding and understand that part but i have no clue about electronics except for basics like safety.

So for the fake sound maker the idea revolves around a usb stick for memory then that plays a sound on a pretty good speaker for good realism i would also like it to be blue tooth so i can change the sound loop from my phone kinda like fishing so i can lure them in based on feel.

I would also like to make mini spy cams wireless that would be pretty fun accessed from phone and be able to flip through the different one and it should be blue tooth like a strong blue tooth that peirces walls.

The motion detector could be silent and ping my phone with the location its at which i would need to type in when im placing it.

if u havent noticed these ideas are kinda r6 inspired.

If anyone has time to help a noob build these please help I could pay for lessons

 

There is a whole lot involved in doing anything with a cell phone, and most of it is software, NOT ELECTRONICS!!
As for motion sensing, the big question is just what variable would you sense to detect motion?? There have been "motion sensors" around for a long time. I built one back in 1965 that used a single tube. It sensed the mains frequency field increase assomebody came near.

The "airsoft devices" that I am aware of are the soft plastic foam pellets shot from toy airguns.

 

All of what you suggest already exists in some form,eg

mini Bluetooth speaker


Wireless motion sensor (ok, this one is wireless/Zigbee not Bluetooth, for more useful range)

etc. AliExpress is full of them!

But its not clear what you want to do? I can show you how to create simple examples of such products just to demo the idea as a learning exercise, using off-the-shelf hobby parts, a working solution though not practical retail products. Designing and manufacturing real products of this nature in those small form factors is not practical without several years experience.

 

Communicating with a cellphone via bluetooth will require creating one end of a physical BLUETOOTH link will require both hardware and software skills, as well as a fair amount of effort. So I would not expect somebody to do it for free.
