SCRATCH CODING KIT
Do you understand the differential gear you learned earlier? Now let's see what is called a steering wheel that is
necessary for an autonomous vehicle to operate.
The driver must turn the handle to change the direction of the car to the left or right. The handle of this car is called
the steering wheel. This steering wheel can be used to control direction.
In the TORI autonomous vehicle, I will use the servo motor to express the steering wheel behavior. I will connect
the servo motor and the front wheel so that I can code the car to run left or right depending on the angle of the
servo motor.

In the picture above, turn the steering wheel to the left, turn on the DC motor and the car will go to the left. Turn
the steering wheel to the right, turn on the DC motor and the car will go to the right. With the steering wheel,
you can change the direction of your car when it runs.
The steering wheel is the direction key of the car. This is because you can control the direction of the
car depending on how you control the direction keys.
