RC Car Basics

What is the main purpose of the **void setup()** function in Arduino?

• It runs continuously in a loop

• It is used to declare variables only

• It runs once to set up pins and settings

• It is used to stop the code

Which function runs repeatedly in an Arduino program?

• void setup()

• pinMode()

• void loop()

• delay()

What is the function of the **pinMode()** command?

• It sets the pin as input or output

• It stops the motor

• It repeats the loop

• It stores values in a variable

In an RC car, which component is responsible for controlling the motors?

• Breadboard

• Motor driver

• Arduino Ground

• Resistor

The **digitalWrite()** function is used to:

• Read data from a sensor

• Send HIGH or LOW signals to a pin

• Declare a variable

• Create a loop

What is the purpose of the **breadboard** in an Arduino circuit?

• To program the Arduino

• To connect different components easily

• To power the Arduino

• To move the RC car

Which voltage pin provides power to the circuit?

• GND

• A0

• 5V

• RX

What does **digitalRead()** do in Arduino?

• Turns the motor on and off

• Reads the value from a digital pin

• Sends power to the Arduino

• Declares a variable

The **L298N Motor Driver** is used to:

• Store variables

• Control the direction and speed of motors

• Connect the Arduino to the computer

• Display text on an LCD

What is the **HC-05 module** used for in an RC car?

• Controlling the car wirelessly using Bluetooth

• Storing programs in Arduino

• Reading analog sensor values

• Controlling the speed of the motor
