Topic: Proximity sensor, detecting distance between two objects (Read 543 times) previous topic - next topic


I wanted to know what would be the best way to wire two objects and have the Arduino know how far away the two objects are. Can I use RFID or is that just either in range or out of range and nothing in-between? I am making an object that has LEDS in side and it changes color as it leaves the range of another object.


Sorry to say this but:-
This sort of thing used to come up a lot a few years ago.

1) There is no way of doing this.

2) You will get lots of people coming up with fancy methods to achieve this. None of these people have actually tried these methods but they are absolutely sure it is easy to do. No one ever reports back any degree of success.
