Could someone please generate a parts list for me?
Arduino (nano ok?)
Wireless Transmitter (which is the lightest, lowest battery consumption with a 30 meter range?)
Battery (I'm hoping to power this with a cellphone battery)
Be able to store and run code to identify and notify the user/s that one or more devices have entered it's range (independently from a PC)
And connect to PC if more notification requirements or code modifications need to be made.
I appreciate help with this project!
