Hello everybody! For a school competition I am designing a nunchuk controlled car. Now, I need to control it from a distance. I can be pretty close to the car, but to be safe I will say 4 feet away.
Currently, the nunchuk directly controls the servos through the same Arduino. I have read about the XBee shield, but I need to be cost efficient, and after watching a video tutorial, the person made it only send 1 number across serial, and he never explained what do for sending big strings across.
I also took a look at bluetooth, but don't know how reliable that is.
My car takes 2 analog pins, 3.3v, and ground directly through arduino. My servos use 4 PWM pins on the board, and a separate power supply.
Please reply what you think I should use, and any libraries and tutorials you suggest. I'm not very good with Serial communication, so thank you for reading!
