Arduino Microcontroller Quiz

The brain of an electronic device, responsible for processing instructions and controlling its functions.

An open-source microcontroller board based on the ATmega328P microcontroller, popular for beginners due to its ease of use and affordability.

Arduino is popular for its affordability, simplicity, cross-platform compatibility, open-source nature, and active community.

A software application that provides a user-friendly interface for writing, testing, and uploading code to a microcontroller.

The toolbar in the Arduino IDE provides buttons for verifying, uploading, creating new files, opening existing files, and saving your work.

Used to check your code for syntax errors before uploading it to the microcontroller.

Transmits the code from your computer to the microcontroller for execution.

A type of signal that carries data in a binary form (HIGH or LOW), representing discrete values.

A continuous signal that can take on any value within a specific range, representing continuous quantities.

An interconnected path that allows electricity to flow, typically made up of electronic components like resistors, capacitors, and diodes.

A circuit where the electric current flows in one consistent direction, usually powered by batteries or DC power sources.

A circuit where the electric current periodically reverses direction, the way household power works.

A measure of the flow of electrical charges in a circuit, represented by the symbol 'A' (amps).

Represents the potential difference in electric energy between two points in a circuit, measured in volts (V).

Indicates how much a component opposes the flow of current in a circuit, measured in ohms (Ω).

The percentage error in the actual resistance of a component compared to its stated value.

A common tool for building temporary electronic circuits without soldering, allowing components to be easily connected and rearranged.

Horizontal strips on the breadboard used to supply power (+ and -) to connected components.

The horizontal crevice that separates the two sides of the breadboard, used to support components and create a barrier between rows.

Vertical connections on the breadboard that allow components to be stacked on top of each other.

Short electrical wires used to interconnect components on the breadboard and Arduino board, providing flexibility in circuit building.

A light-sensitive device that changes its resistance based on the intensity of light, used to measure light levels.

A semiconductor light source that emits light when an electric current passes through it, commonly used for indicating or lighting.

A technique used to simulate an analog output by varying the width of digital pulses, controlling things like LED brightness and motor speed.

The percentage of time that a digital signal is HIGH within one cycle, determining the power level in PWM.

A small electronic device that produces sound by vibrating piezoelectric material when electricity passes through it.

Used to play a tone on a piezo buzzer connected to an Arduino pin.

Stops the tone being played on a piezo buzzer, silencing it.

A sensor that uses high-frequency sound waves (ultrasonic) to measure the distance to objects.

A common type of ultrasonic sensor that's used for proximity detection and ranging measurements.

An electric motor that converts direct current electrical energy into rotary mechanical energy, used for rotation and speed control.

An integrated circuit (IC) that controls the direction and speed of DC motors, often used in robotics projects.
