Chip lm393 compared the resistor value, when there is an imbalance, the chip will control one motor to stop, while other motor accelerate rotation, in this case, the car can correct direction. The whole process is closed-loop control, so it can be quickly controleed

The WiiChuck Adapter is a small PCB that is designed to be inserted into the connector of a Nintendo Wii Nunchuck to provide access to all 4 wires of the remote. The power, ground and two-wire interface of the Nunchuck are all broken out to a 4-pin 0.1" pitch header. Compared with standard WiiChuck, the DFRobot WiiChuck has extra 4 pins which allow you connect it to two devices.
The Wii Nunchuck is loaded with features -- a 2-axis joystick,
two buttons and a 3 axis ±2g accelerometer -- and any device capable of I2C can communicate with it! The WiiChuck allows you to interface with the Nunchuck without making a mess and cutting the wires.
