Summative Assessment on Arduino Input Devices

What is the primary purpose of an input device in Arduino?

• To produce actions or display information

• To collect data from the environment and send it to the Arduino board

• To power the Arduino board

• To store data for future use

Which of the following is an example of an Arduino input device?
