Which function in Arduino executes only once when the board is powered on?

• loop()
• delay()
• setup()
• pinMode()

What is the purpose of the loop() function in Arduino?

• To execute setup configurations
• To define data types
• To execute code repeatedly
• To configure communication channels

Which function is used to configure a digital pin as an input or output?

• pinMode()
• digitalRead()
• digitalWrite()
• analogRead()

What does the analogRead() function in Arduino do?

• Reads the state of a digital pin
• Writes a value to an analog pin
• Reads the voltage of an analog pin
• Configures a pin as an input or output

Which function is used to send data to the serial port in Arduino?

• Serial.begin()
• Serial.print()
• Serial.read()
• Serial.available()

What does the delay() function do in Arduino programming?

• Executes code once
• Pauses the program for a specified time
• Reads incoming serial data
• Writes data to the serial port

What is the purpose of local variables in Arduino programming?

• They offer data sharing across functions
• They are limited to specific functions
• They are defined outside any function
• They are accessible from anywhere in the sketch
