In this paper we shall take a brief look at the Arduino microcontroller and some of its applications and how
it can be used in learning. Arduino is an open-source microcontroller used in electronic prototyping. Arduino hardware and its
components shall be looked at. Software and the Environment that Arduino runs on are both looked at too. Some applications
will be taken as examples that can help make learning Arduino more interesting. This can be used as a major way to encourage students and others to learn more about electronics and programming
