I am a complete rookie to electronics and would like to start a new Arduino project.
The project will involve basically:
Any recommendations on websites to buy components for this will be greatly appreciated as well.
(I currently need to purchase Arduino and need advice on the above project and relevant purchases!)
what sort of range/distance are you looking at?
obviously if its like a mile/km then you would need to use gps or something
I’m looking for a variable range - like 2x settings.
-1st setting would make an alarm go off at 4metres
-2nd setting would make an alarm go off at 8metres
Is this possible?
Would be difficult to get the Arduino to recognise the strength of the signal and determine/translate this into distance?! :-?
My Arduino starter kit arrives tomorrow!
Please don’t cross post, there are people wasting their time answering questions that have already been answered.

Yes it is difficult.
Signal strength is not a very reliable indicator of distance, due to reflections.
