Scenario:

You are a junior computer engineer at a company that manufactures remote and radio control cars. Your R&D team is currently working on designing a new line of RC cars, which requires your knowledge on microcontrollers to make integral design decisions for upcoming products.

The design has the following base requirements:

Driving multiple DC motors for wheels

Buttons and joysticks on the controllers to accelerate, brake, reverse

Status LED's

Ultrasonic distance sensors for automatic braking

LCD display speedometer

Task $1$

Base on the above design $($ATmega $2560)$ microcontroller was selected as the most appropriate microcontroller for this project.

Task $1\mathrm{.}1$

Provide an evaluation of the selected microcontroller architecture and subsystems, exploring key electrical characteristics, timing, memory capabilities, interrupt capabilities, ALU size $($instruction width$).$

Task $1\mathrm{.}2$

Perform a more detailed critical evaluation of the microcontroller characteristics and subsystems, highlighting its applicability to the design criteria specified

Task $2$

Your boss is of the opinion that the company should branch off into the production of Unmanned Aerial Vehicles $($UAVs$)$ or drones, which will potentially have autonomous capabilities. This means that these units would require a GPS system. In no more than two pages, explein how embedded systems can include GPS subsyslerms and be interfaced with the Internet of Things $($loT$).$

Task $2\mathrm{.}1$

Identify trends of embedded systems in loT$-$enabled spaces

Task $2\mathrm{.}2$

Of the trends identified in Part $2\mathrm{.}1$ above, critically evaluate those trends, identifying technical and economie factors and their impact on loT techinology
