So I want to build a robot powered by an arduino uno rev 3 for my science fair project. I want to compare tank control and joystick control. I will do this by building a race track and time how fast each type of control completes the race. My problem is that I don't know how to connect a controller to it. I have seen that I can control the robot with usb host by using a Bluetooth dongle to connect a PS3 controller to it. Also I've heard that you can control the robot over wifi. I'm a beginner in robotics and have little experience with coding. The science fair is in a month and I would appreciate it a lot if anyone could help.
This is the link to the video I saw:
