i have a lot of DC motors at home... never bought a servo cuz they're costly, even the ones online need to be modded for continuos operation..so i never bothered with them..
So far the only manually controlled bot i've made was using L293D and rc from a toy car.. that didn't end so well...
RF modules are costly here as well.. I'm willing to buy an MCU and servo if i can cut costs on atleast the RC.. i've read about interfacing via bluetooth but its all quite ambiguous on SOR,and if not..there's the 94$ AXON MCU which again..a full-time student like me can't afford..
I need to know what's what about wireless control for my robot via pc... preferably compatible with dc motors or otherwise(servos)..
