How to make a simple wireless digital communication circuit? Answered
Hey, i want to make a simple wireless digital communication circuit. This is not exactly what i'm going to do, but this is the easiest way to explain it: watch the image below. What should i build inside "box ?(1)" and " box ?(2)", to make the 2 LEDs turn on when i push the button? The first circuit should be like a transmitter and the seconds one a receiver, but i just don't have any idea how to make this simple circuit. I don't really know what frequency it should be at.. What's the easiest to make and works for the longest distance without problems with background radiation?
(I'm sorry if this is a stupid question but i really a noob in hardware development... :p )
Thanks for helping!
