Understanding Arduino and Motor Control

What is the primary function of an Arduino Uno?

• To act as a simple calculator for mathematical operations.

• To function as a power supply for other devices.

• To serve as a basic storage device for files.

• To serve as a microcontroller board for creating interactive electronic projects.

Which programming language is commonly used for Arduino programming?

• Ruby

• C/C++

• Python

• Java

What is the purpose of the digital pins on an Arduino Uno?

• The digital pins are used for reading and writing digital signals.

• The digital pins are meant for connecting to Wi-Fi modules.

• The digital pins are exclusively for power supply.

• The digital pins are used for analog signal processing.

How do you power an Arduino Uno?

• Use a solar panel with no voltage regulation

• Connect directly to a 24V power supply

• Power an Arduino Uno via USB, barrel jack, or Vin pin with 7V to 12V.

• Power via a standard 9V battery without a regulator

What is the function of the analog pins on an Arduino Uno?

• The analog pins store data in EEPROM.

• The analog pins read analog signals and convert them to digital values.

• The analog pins are used for power supply.

• The analog pins output digital signals only.

What is PWM and how is it used in motor control?

• PWM is a type of motor that runs on batteries.

• PWM (Pulse Width Modulation) is used in motor control to adjust the speed and torque by varying the duty cycle of the power signal.

• PWM is a method for measuring motor temperature.

• PWM is used to increase the voltage in electrical circuits.

What type of motor can be controlled using an Arduino?

• Induction motors

• DC motors, stepper motors, and servo motors

• AC motors

• Brushless motors

What is the difference between a DC motor and a stepper motor?

• A DC motor is used only in robotics, while a stepper motor is used in household appliances.

• A DC motor operates at a constant speed, while a stepper motor cannot change speed.

• A DC motor requires a microcontroller, while a stepper motor does not need any control system.

• A DC motor provides continuous rotation, while a stepper motor allows for precise control of position in discrete steps.

How do you connect a motor to an Arduino Uno?

• Connect the motor to a Raspberry Pi instead of Arduino.

• Use a motor driver to connect the motor to the Arduino Uno.

• Connect the motor directly to the Arduino pins.

• Use a battery to power the motor without Arduino.

What is a motor driver and why is it used with Arduino?

• A motor driver is used to power Arduino directly.

• A motor driver is only needed for DC motors.

• A motor driver is used with Arduino to control motors safely and effectively.

• A motor driver is used to increase the speed of Arduino.
