The Arduino Platform and C Programming Quiz Answers

About The Arduino Platform and C Programming Course

The Arduino is an open-source computer hardware/software platform for building digital devices and interactive objects that can sense and control the physical world around them. In this class, you will learn how the Arduino platform works in terms of the physical board and libraries and the IDE (integrated development environment).

You will also learn about shields, which are smaller boards that plug into the main Arduino board to perform other functions such as sensing light, heat, GPS tracking, or providing a user interface display. The course will also cover programming the Arduino using C code and accessing the pins on the board via the software to control external devices. Please note that this course does not include discussion forums.
