Question

A function is a series of programming statements that can be called by name. Which command is called repetitively over and over again as long as the Arduino has power.

A.loop()
B.(output)
C.setup()
D.(input)

Answer 1

The loop() function in an Arduino program is called repetitively until the Arduino board is powered off or reset. It's where the primary code that controls the Arduino's operations is located, following the initial setup within the setup() function.

Step-by-step explanation:

The command that is called repetitively over and over again as long as the Arduino has power is loop(). In the context of Arduino programming, functions are blocks of code that perform particular tasks and can be executed when called.

The Arduino environment has two main functions: setup() and loop(). setup() is called once when the Arduino is powered on or reset; it's often used to initialize variables, pin modes, start using libraries, etc. After setup() runs, the loop() function is called repeatedly, allowing the device to change and respond. It's where the main part of your code will reside. This loop continues until the board is powered off or reset.
