LED blink based on proximity Answered

Hi,

I want a LED to start blinking if it is outside some area. Kind of a prisoner electronic bracelet :)

What would be a cheap solution for this? Could I do this with 2 proximity sensors?

Thank you.

Thank you, first of all.

The goal is similar to the image attached. I want a led to start blinking if it is outside the base perimeter.. the distance would be configurable,
