Week 4 - Microcontroller Group Assignment

A microcontroller is a small self-contained computer on a single integrated circuit (IC) that controls specific devices within electronic systems. It is programmed using a specialized computer language and can execute instructions stored in its memory. A microcontroller is also called an embedded controller or microcontroller unit (MCU). Microcontrollers are commonly used in various applications, such as robotics, automotive, consumer electronics, and medical devices. They are preferred over other processors due to their low cost, low power consumption, and small size. All this makes them an ideal choice for embedded systems.


What's the name of the microcontroller (include a picture)

How Many pins does your microcontroller have

What are the types of pins your microcontroller has

What type of sensors does your microcontroller have embedded on it directly? (if any) 

What is your microcontroller’s operational voltage? 

What type of languages can you program it with

List of connectivity options (Can it connect to wifi? Bluetooth? Neither?)

Arduino UNO has no embedded sensors as they are focused to provide a simple platform to be able to add your own desired sensors.

3.3V, 5V

The most functional language for it to be programmed with would be C++.


But there are some alternatives such as Python and Visual Programming Languages.


Although, for beginners it is possible to use different programming languages such as blocky programmes such as Scratch or BlocklyDuino but they will not be offering the same level of function as C++

As arduino UNO is created to be an affordable and beginner friendly device it is made to not have WiFi connection nor Bluetooth and gives the option for the users to do what they want.
