I'm trying to understand if it's possibile to send voice in real-time between 2 Arduino via wireless. Something like a unidirectional Walkie Talkie. Something like that:
Microphone - Arduino - TX ---------------> RX - Arduino - Speaker
I would like to use this mic: http://www.sparkfun.com/products/9964 I see the AUD pin and I assume I should connect it to the PWM pin on board, but I really don't know what kind of values are read and how to send it in real-time.
Assuming that is easy to find a AD/DA converter to be connected on the PWM, the other problem is the wireless transmission. The first solution was Zigbee, but we concluded in other posts that is not a solution for the problem. Any other ideas ?
Thanks in advance for your answers.
