Arduino Self-Driving Car Lesson 1: Controlling a Motor

This video tutorial explains how to control a DC motor using an Arduino. It covers the basics of electrical current, the necessary components, and how to build the circuit. The tutorial also demonstrates coding techniques to control the motor's direction and speed, using both basic and advanced methods. The use of Tinkercad Circuits for simulation is highlighted, providing a visual aid for understanding the circuit setup.

Why is an external battery pack necessary when controlling a motor with Arduino?

• Motors require more current than Arduino pins can supply.

• Arduino pins can provide enough current for motors.

• Arduino pins can supply unlimited current.

• Motors do not require any current.

What is the purpose of a common ground in a circuit?

• To connect the circuit to the internet.

• To ensure all parts of the circuit share a common reference point.

• To connect all positive voltages together.

• To increase the voltage in the circuit.

Why should the H bridge be placed across the middle gap of the breadboard?

• To ensure it is not connected at all.

• To make it look symmetrical.

• To short circuit the pins on opposite sides.

• To prevent short circuiting pins on opposite sides.

What is the role of the enable pin on the H bridge?

• To disable the motor permanently.

• To control the speed of the motor.

• To provide power to the Arduino.

• To connect the motor directly to the battery.

What should you do if your motor does not spin when connected to the circuit?

• Replace the motor immediately.

• Check the battery pack and connections.

• Remove the H bridge from the circuit.

• Increase the voltage from the Arduino.

How can you reverse the motor's direction using code?

• By using two different pins to control direction.

• By changing the motor's physical position.

• By swapping the motor's wires.

• By increasing the voltage.

What is the benefit of using functions in your Arduino code?

• To simplify and organize repetitive tasks.

• To prevent the motor from spinning.

• To make the code longer.

• To make the code run slower.

What does the 'void' keyword indicate when defining a function in Arduino?

• The function returns a value.

• The function does not return a value.

• The function takes multiple arguments.

• The function is optional.

How can you make the motor stop for a specific amount of time using functions?

• By using a delay command inside the function.

• By removing the power supply.

• By disconnecting the motor wires.

• By using a higher voltage.

What is the advantage of passing arguments to functions in Arduino?

• To make the code more complex.

• To allow functions to perform tasks with different inputs.

• To make the motor spin faster.

• To increase the size of the program.
