Arduino Uno as an Easy to Use Microcontroller for the Non-Engineer

Introduction

The microcontroller, Arduino, was created in 2005. Before then, a consumer would choose between either a PIC (Peripheral Interface Controller) microcontroller or a FPGA (Field Programmable Gate Array). Although both cost less money, they are difficult to understand and use. Although Arduinos are more expensive, they offer many benefits. Arduinos have their own USB interface controller on the PCB (Printed Circuit Board) which allows for easier connectivity between the Arduino and the computer. Another benefit is that the microcontroller, the ATmega328, is already configured on the PCB so that the inputs and outputs are ready to use. Another benefit to Arduino is that the programming Language is similar to C and is easy for a beginner to learn.

Purpose

1. To establish the pros and cons of the Arduino

2. Shield use, and how to extend the functionality of an Arduino

2. Possible Uses for an Arduino

3. Construction and Accuracy of the Arduino

5. Final conclusion on the Arduino

Methods

Secondary research was primarily used. Electronic sources are the main type of secondary source, with a few from interview, and from print. There was a small amount of primary research as well, through my experience with Arduino in the Sylvania Engineering Club.

Background on Arduino Microcontroller

A microcontroller is essentially a very small computer on a single IC (integrated circuit). On the Arduino, there is a Atmel Atmega328 microcontroller, which allows the user to create a program for their circuit to follow. For example, say that you wanted to make an LED (light emitting diode) blink on and off with a one second delay in between, instead of using an IC to create a 1Hz square wave, you could use an Arduino and a simple program t...
