Thanks for sharing
So I want to make a sensor that glows when in range of the transmitter… And to anyone including me this sounds easy…till I want it to be no larger that a 50 cent piece; although it needs to only work within 50 yards or so.
Please help, I want it for my friends Christmas present.
Lastly can you please explain what of the two “rf inputs” as suppose to go to.
Thank you for this post!
