Arduino Self-Driving Car Lesson 2: Steering with Two Motors

This video tutorial guides viewers through the process of controlling two motors using an Arduino to build a robotic car. It covers the necessary components, circuit building, and programming functions to control motor movements. The tutorial also includes testing and debugging tips, as well as adding a power switch for easy control. The use of Tinkercad Circuits for simulation is demonstrated, and viewers are encouraged to follow along with their physical Arduino setup.

What is the purpose of using a 9 Volt battery with a snap connector in the Arduino motor project?

• To power the Arduino without a USB connection

• To power the motors directly

• To increase the speed of the motors

• To provide backup power

Why is it important to disconnect the battery pack and USB cable before working on the Arduino circuit?

• To save battery life

• To reset the Arduino

• To update the firmware

• To prevent accidental short circuits

What is the function of the enable pin in the motor control circuit?

• To control the motor's speed

• To reverse the motor's direction

• To connect the battery pack

• To power the Arduino

How can you ensure that your wiring is neat and easy to debug on a breadboard?

• Avoid using jumper wires

• Keep wiring symmetrical and organized

• Use wires of the same color

• Use longer wires

How can you make a robot turn left using two motors?

• Spin the left wheel forward and the right wheel backward

• Spin the left wheel backward and the right wheel forward

• Spin both wheels backward

• Spin both wheels forward

What should you do if your robot spins instead of driving forward when testing the drive forward function?

• Change the motor type

• Add more power to the motors

• Reverse the pins for one or both motors

• Increase the motor speed

What is the first step in writing functions to control both motors in the Arduino project?

• Test the motor directions

• Set the motor speed

• Declare variables for the motor pins

• Connect the motors to the Arduino

What is the purpose of the slide switch in the Arduino motor project?

• To connect the Arduino to a computer

• To control motor speed

• To turn the vehicle on and off easily

• To change motor direction

Which component is used to control the speed of the motors in the Arduino project?

• Digital Write command

• Slide switch

• L293 DH bridge

• Analog Write command

What should you do if your vehicle doesn't drive perfectly straight?

• Adjust the motor speed using Analog Write

• Replace the motors

• Use a different battery pack

• Rebuild the chassis
