Im currently building a rov and am considering using a arduino to control it. I was considering the Uno since this is the only 1 available here
but since im new to all this i still have some questions
1.Can a arduino Uno control 4 brushless esc's + motors and 4 relays at once? (motors and relays have to all be separatly controllable). Does the uno have enough channels/outputs to control all these functions at once. Would there still be ports open to control more functions?
2.Would i need some kind of shield to run the esc's and motors or can they be connected directly to the Uno?
3.Could i control the motors via a joystick connected to pc with usb(for variable speed)
4.Probably a stupid Q but the arduino cant be used when not plugged into a pc right?
If someone could help me here i would really appreciate it
Sorry if some of the questions are stupid, im still new to all this
