Hi, I'm about to start on project in which i will need data transmission...
I need to transmit only few bytes in radius of 2-5 meters...
I need some super cheap and the most compact way how to do it. Bluetooth and wi-fi modules arent very cheap and LED trasmission wont probably also work, because 2 "nods" wont see each another...RF seems to be the best way...I've read RC tutorial on this page, but this variant isnt "compact enough"...
Are there some RX and TX ICs in good price?
Some good tutorial how to use those ICs will be handy too...
Thanks
