Looking for some sort of simple solution for the following....
Want to transmit an audible "beep" from a headphone jack, wirelessly to an LED that will blink at the same interval, or even just light up (doesn't necessarily have to blink).
Without building a circuit from scratch, is there some components I could cobble together to accomplish this?
I.e., I could tear apart a cheap $10 2ch RC car, and use the audio signal to trigger the transmitter?
Just looking for some idea's, maybe another approach I haven't thought off.
