yes correct ....it supports to use the cheapest rf 433mhz modules.....
the only library that deals with such thing is VirtualWire library , do you have any opinion about a similar more efficient library??
i have already applied for nRF24L01 on ebay it seems to be the solution of getting rid of VirtualWire because i am sure now that is is the problem , how ever i dont prefer to use nRF24L01 because it uses SPI protocol , and i want to make this matter the simplest i can ,,,, but Arduino micro controller disappointed me.
