So we have this project where we have to invent/innovate something. I had this idea where a tracking device which gives you signals to the location of the product you're looking for is attached on your shopping cart.

Does anyone know how to make this realistic? like what parts do you need to make this? and probably how much for each component

Thanks in advance!

you'd probably want a custom solution in the end, but I'd recommend making a proof of concept first, so you'd probably want to use arduino or a microprocessor to start, we can also talk on discord, I am on the server, and my username is DaSniper#5252
