Hi Guys,
I used to program directly with AVR's but am loving the easy Arduino libraries.
I want to produce a wireless transimssion of a message when a buton is pressed, and another arduino receives it. I know boards already exist to help do this, but I came across this:
http://www.swharden.com/blog/2011-08-06-ridiculously-simple-avr-mcu-am-radio-transmitter/
The hardware here is super simple. I know it is messing with fuses to get the 1Mhz ckOut but I thought I could set up a hardware interupt pin at 1Mhz based on the built in 16Mhz clock on my Arduino.
Apart from that the rest of the code looks easy to replicate. Then set up a button to send the message rather than loop the message out forever.
But Now for receiving. And maybe Im in the wrong forum because this is more of an electronics question.
Can I use the same circuitry as in the above link, and just change the code to "receiving code"? Im not sure what it would have to do, but i am imagining something like another interupt timer, also set to 1Mhz listening to data coming in on an analog pin - or maybe continuous listening, because the two devices might be completely out of sync.
Any experts in this field be able to advise me here.
P.S The reason i am looking at this circuit is because I am after a very small transmitter, and exisitng decives are quite bulty in comparison to how small and adaptable this one could be.
