Signal Indicator? Answered
I'm trying to make a simple transmitter/receiver setup to use in airsoft to keep track of the distance (not worried about direction right now) between me and whatever the transmitter is planted on. The transmitter can send out a steady signal or pulses, and the only problem I have is how it will show the distance. I have a line of LEDs that I want to set up so that more light up the closer I get to the transmitter, but I don't know how to rig the setup so that it displays signal strength (I would think that the closer you are the stronger the signal). Does anyone have any idea how I can do this or perhaps better alternatives that accomplish the same thing?
