i want to try some robotic project with adruino so i need wireles solution for comunication. Since i have no RC transmitter for RC cars etc. i decided to use PC/laptop as controller, first thing i found was XBee, but after a while on ebay i found much cheaper solution:
link on ebay
My question is simple, would i be able to send some specific command probably hexa code or string, for simplicity let’s say “turn left” from PC, transmit it throught this to adruino where will be proly some switch statement with functions for servos etc. ? Ofcourse controlling from serial monitor is only for lifting up. And if XBee and this is basicaly doing the same thing, why is XBee almost 4 times as expensive? Maybe it’s completely bad idea, but i thought computer would give me no limited controlling interface.
I’ll be happy for any opinion or help.
