What is Arduino? Answer: Arduino is an open-source electronics platform based on easy-to-use hardware and software.
What is the difference between Arduino and Raspberry Pi? Answer: Arduino is a microcontroller platform, whereas Raspberry Pi is a single-board computer.
What are the basic components of an Arduino board? Answer: The basic components of an Arduino board are the microcontroller, USB port, power jack, reset button, and pins.
What is a microcontroller? Answer: A microcontroller is a small computer on a single integrated circuit that is designed to control specific devices or systems.
What is a pin? Answer: A pin is a physical connection point on an Arduino board that can be used to input or output electrical signals.
What is a breadboard? Answer: A breadboard is a tool used to prototype electronic circuits by allowing the easy insertion and removal of electronic components.
What is a resistor? Answer: A resistor is an electronic component that resists the flow of electrical current.
What is a capacitor? Answer: A capacitor is an electronic component that stores electrical energy.
What is a LED? Answer: A LED (light-emitting diode) is an electronic component that emits light when current flows through it.
What is a servo motor? Answer: A servo motor is a type of motor that can be controlled precisely to move to a specific position.
What is a sensor? Answer: A sensor is an electronic component that can detect changes in the environment and provide a signal or output.
What is a potentiometer? Answer: A potentiometer is a variable resistor that can be adjusted to change the resistance and control the flow of electrical current.
How do you upload a program to an Arduino board? Answer: To upload a program to an Arduino board, connect the board to a computer via a USB cable, open the Arduino software, select the appropriate board and port, and click the upload button.
What is the Arduino IDE? Answer: The Arduino IDE is the software used to write and upload code to an Arduino board.
What is a sketch? Answer: A sketch is a program written in the Arduino IDE that is uploaded to an Arduino board.
What is the setup() function in an Arduino sketch? Answer: The setup() function is a predefined function in an Arduino sketch that is executed once at the start of the program to initialize the board.
What is the loop() function in an Arduino sketch? Answer: The loop() function is a predefined function in an Arduino sketch that is executed repeatedly as long as the board is powered on.
What is the pinMode() function used for? Answer: The pinMode() function is used to set the mode of a pin as either input or output.
What is the digitalWrite() function used for? Answer: The digitalWrite() function is used to write a digital value (either HIGH or LOW) to a pin set as output.
What is the analogRead() function used for? Answer: The analogRead() function is used to read the value of an analog pin.
What is the analogWrite() function used for? Answer: The analogWrite() function is used to write a PWM (pulse width modulation) signal to a pin set as output.
What is the delay() function used for? Answer: The delay() function is used to pause the execution of a program for a specified amount of time.
What is serial communication in Arduino? Answer: Serial communication in Arduino is a way to send and receive data between the board and a computer or other device.
