Question

Which of the following statements is not true when dealing with the Firmata library?

(a) The Firmata Library is used to establish communications between the Arduino and the Desktop

(b) The Firmata Library uses the Firmata Protocol for communicating data

(c) The Firmata Library uses the Midi Message Format

(d) The Firmata Library can only be used on an Arduino Uno

This question was addressed to me in class test.

My question is taken from Standard Libraries in chapter Arduino Programming of Arduino

Answer 1

The correct answer is (d) The Firmata Library can only be used on an Arduino Uno

To elaborate: The Firmata Library is used for communicating data to and from the computer. This is required when the Arduino is required to store certain data on the computer which would be otherwise too large for the Arduino to store in its internal memory. Other uses of this library are in the field of IOT.
