Arduino and Servo Motors Quiz

An open-source platform consisting of both hardware (a microcontroller board) and software (the Arduino IDE) for creating interactive electronic projects.

A microcontroller with input/output pins used to connect and interact with external electronic components like sensors, motors, and LEDs.

The Arduino Integrated Development Environment (IDE) is a software program used to write and upload code (sketches) to the Arduino board.

One of the most popular Arduino boards, known for its balance of simplicity and functionality. Ideal for beginners.

A microcontroller with 14 I/O pins (6 PWM outputs), 8 analog input pins, and a 32 KB flash memory.

A smaller and more compact version of the Arduino Uno, often used in projects where space is limited.

Similar to the Uno, it has 14 I/O pins (6 PWM), but only 6 analog input pins. It is designed for breadboards.

A larger Arduino board with more memory and more I/O pins, often used for more complex projects.

Provides 54 digital I/O pins, with 15 supporting Pulse Width Modulation (PWM) outputs, for controlling various electronic components.

Offers 16 analog input pins for reading analog signals from sensors like potentiometers, light sensors, and temperature sensors.

The primary software used to write, compile, and upload code to Arduino boards. It simplifies programming with its user-friendly interface.

The main part of an Arduino sketch, where you write the instructions for your program. It includes functions like setup() and loop().

Executed once when the board powers up or resets, and is used to configure settings like setting pin modes and establishing communication.

Executed repeatedly after the setup() function, forming the main logic of your program. It defines the actions that run continuously.

A feature within the Arduino IDE that allows you to monitor and communicate with your Arduino board via serial communication. It's useful for debugging and data display.

The "Port" option allows you to select the specific communication port your Arduino is connected to on your computer, typically a COM port.

Digital pins in Arduino can be configured to either send signals out (OUTPUT) or read signals in (INPUT). They can also be set as input with an internal pull-up resistor (INPUT_PULLUP) for more advanced applications.

The pinMode() function sets the direction (input/output/pull-up) of a digital pin. It requires the pin number you want to configure and the desired mode (INPUT, OUTPUT, INPUT_PULLUP).

The digitalRead() function checks the state of a digital pin and returns a value of 0 (LOW) or 1 (HIGH) indicating the signal level on that pin. We can read the state of a digital input pin using this function.

Serial communication allows the Arduino board to interact with your computer using a text-based format. It's useful for debugging, sending messages from the Arduino to your computer, and receiving commands from the computer.

The Arduino IDE's Serial Monitor is a window that lets you display text-based data (like sensor readings) coming from your Arduino and also allows you to send text commands to the Arduino over the serial port.

Libraries provide reusable code modules to extend the Arduino's functionality. Libraries are designed to work with specific components, such as sensors, displays, or communication protocols, making it easier to work with them.

The Serial Plotter within the Arduino IDE allows you to visualize live data coming from your Arduino. You can graph and analyze specific data points over time to gain insights into your program's behavior.

A ratio representing the proportion of time a device is 'on' compared to its total operating period. It affects power delivery and can be adjusted to control the intensity or speed of a device.

A type of motor that can be precisely controlled in terms of its position, speed, and acceleration. It uses a feedback system to ensure it stops at the desired angle.

A type of servo motor that can rotate continuously in either direction, making it ideal for applications requiring speed and direction control.

A very compact type of servo motor often used in small, space-constrained projects like drones or robots.

Pulse Width Modulation (PWM) is a method of controlling a device's power by varying the width of a pulse signal. The wider the pulse, the more power is delivered.

Reads the state (HIGH or LOW) of a digital pin.

Sets a digital pin to either a HIGH or LOW state.

Reads the analog voltage on an analog pin and converts it to a digital value between 0 and 1023.

Writes an analog-like output to a digital pin using Pulse Width Modulation (PWM).

A technique for controlling electrical devices by changing the width of pulses in a square wave. It's used to simulate analog signals in digital systems.

The percentage of time the signal stays HIGH during each cycle in a square wave.

How often the signal switches between HIGH and LOW in a square wave.

Determines the average power delivered to the load, making PWM a useful technique for controlling the amount of power.
