[hobbitababord]

do you know the distance of the emission ?

[BlanchProductions]

@hobbitababord Depends on how big your antenna is, the longest i got it was about 40ft. Maybe You could try putting an op-amp on it??

@hobbitababord Depends on how big your antenna is, the longest i got it was about 40ft. My latest theory, yet to be tested, is to run the output signal through an op-amp....hmmm

[JosephFallon1]

The arduino runs at 16 MHz so the actual frequency is 1333.33Khz not 1337 since the transmit frequency must be an integer fraction of 16MHz. Since it is a square wave you will have a pretty wide bandwidth though.

@JosephFallon1 Jesus we've found someone who knows what they're talking about! Comment very much appreciated

[geliegelie]

can you send me the circuit diagram of this??.,

together with pats list.,

thanks a lot

[BlanchProductions]

@geliegelie Your kidding right...uh...link in the description DUDE... -.-

[bit4shift]

Your code is all messed up!!! Next time pay attention when you post Arduino/C++ code to your own website!

[Chipudnik]

"if you have an arduino and no copper wire, well then you're REALLY stupid" HAHAHAHA great vid :D

[part15er]

Just so no one is confused, am antennas in most receivers are built inside of the radio. Extending the FM Telescopic antenna on your radio will not improve reception of AM Frequencies.

THE CODE DOESN'T WORK!

[OopsIDied2]

this is pretty badass lol thanks. i'm gonna try to make my arduino transmit from my mp3 somehow...

[hobbitababord]

@BlanchProductions Ok thank you !

I asked myself if it's possible to make a radio communication between two or more arduino.

I've already made à cell-phone wave detector (but i d'ont know you can choose the frequency)

so maybe it's possible !!
