Arduino 2025

Which Arduino function is used to write a HIGH or LOW value to a pin?

• digitalRead()

• analogRead()

• digitalWrite()

• analogWrite()

This function is used to set a pin as being either an INPUT or OUTPUT

• digitalRead()

• pinMode()

• digialWrite()

• setup()

This keyword is used to force the CPU to read a value from memory (RAM)

• const

• int

• volatile

• bool

This function is used to pause the execution of code for a specified period of time in milliseconds

• analogRead()

• analogWrite()

• digitalRead()

• delay()

This coding technique is used to pause the execution of code to respond to an external event, such as a button press

• for-loop

• void loop()

• interrupt

• delay

This function is used to print values to the Serial Monitor, making it very useful for inspecting values and debugging code.

• Serial.begin()

• Serial.println()

• Serial.printLine()

• Serial.close()

What does the coding principle "DRY"

• Don't read yearbooks

• Debug, Retry, Yell

• Desperately removing yellow

• Don't repeat yourself
