Use case diagram A use case diagram at its simplest is a representation of a user’s interaction with the system that shows the relationship between the user and the different use cases in which the user is involved. A use case diagram can identify the different types of users of a system. The different use cases and will often be accompanied by other types of diagrams as well.

CHAPTER 4 HARDWARE DESCRIPTION 4.0 Arduino: The Arduino Uno is a microcontroller based on the ATmega328. It has 14 digital input/output pins in which 6 can be used as PWM‚ 6 analog inputs‚ a 16 MHz ceramic resonator‚ a USB port‚ a power jack‚ an ICSP header‚ and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.[11] The Uno differs from all preceding boards in
