What is Arduino and can I use it for my project? [Beginner Friendly]

What is Arduino?

Introduction to Arduino

  • The instructor introduces the concept of Arduino, questioning its recognition and likening it humorously to a sub sandwich.
  • The lesson aims to clarify what Arduino is, its popularity, and whether it's suitable for viewers' projects.

Understanding Arduino's Functionality

  • Arduino serves as a tool for controlling electronics, similar to how a pencil aids in writing.
  • It categorizes electronic devices into inputs (e.g., sensors like temperature and light sensors) that gather information and outputs (e.g., motors and displays) that perform actions.

Components of Arduino

  • There are three main components of an Arduino: the physical board (like the popular Arduino UNO), the software (Arduino IDE), and the code written for it (called sketches).
  • The microcontroller on each board acts as a small computer enabling interaction with inputs and outputs.

Why is Arduino Popular?

Accessibility of Microcontrollers

  • Traditionally, using microcontrollers was complex; however, Arduino simplifies this process making it accessible to non-engineers.

User-Friendly Design

  • The hardware design allows easy connection via USB cables and simple component attachment through headers on the board.
  • The built-in external power jack enables operation without being connected to a computer.

Simplified Software Experience

  • The Arduino IDE prioritizes simplicity over complexity, allowing users to write code easily without distractions.
  • Functions within the code facilitate reading inputs and controlling outputs efficiently compared to traditional programming methods.

Understanding Arduino: Simplifying Complexity

The Arduino Ecosystem

  • The Arduino language simplifies programming by providing straightforward functions, making it easier to control various components.
  • The Arduino IDE is user-friendly, and the code is easy to understand, contributing to its popularity among users.
  • Open-source hardware allows multiple companies to create compatible boards, expanding the ecosystem of available resources and support.
  • Affordability of Arduino hardware plays a significant role in its widespread adoption for projects.

Identifying Suitable Projects for Arduino

  • Most Arduino projects involve an input (e.g., sensors), logic processing, and an output (e.g., actuators), forming a basic operational structure.
  • Inputs can vary in complexity; for instance, conditions may include temperature ranges or time factors influencing outputs like lights or motors.
  • While suitable for many applications, Arduino may not be ideal for high-demand tasks such as video processing or large computations due to its microcontroller limitations.

Encouragement and Next Steps

  • Viewers are encouraged to explore their creativity with Arduino projects and consider watching additional content that showcases exciting project ideas.
  • Engagement with the audience is invited through comments about potential projects they wish to build using Arduino.

Maybe you’ve seen some projects that use an Arduino? What is this Arduino thing anyway? Sounds like a sub sandwich.Arduino sub sandwich In this video, we’re going to use plain language to tell you exactly what an Arduino is. YOU WILL LEARN What exactly an Arduino is Why it’s so wildly popular If Arduino is right for your project WHAT IT IS EXACTLY The best way to explain what an Arduino is will be to start with what you can use it for. Put simply, an Arduino is a tool for controlling electronics. Think about a pencil. A pencil is a tool to help you write stuff. You need to write something down so you could grab a pencil. Same idea with Arduino. But Arduino is a tool for controlling electronics. Arduino pencil If you need to control some electronic stuff, hey, grab an Arduino. But what do we mean by electronic stuff? Well let’s define two general groups of “electronics stuff”. We’ve got inputs, and those would be electronic devices that gather information. We also have outputs, those would be electronic devices that do things. For inputs, you can think of all the types of sensors out there: temperature sensors, light sensors, touch sensors, flex sensors, humidity sensors, infrared sensors, distance sensors, to name a few.Arduino inputsYou can think of those sensors as input devices, and those types of sensors can be read by an Arduino board. Now outputs would be things like DC motors, stepper motors, servo motors, solenoids, LCD displays, LED indicator lights, speakers, and electrical stuff that have some type of action in the world.Arduino OUTPUTSSo Arduino can be used to read inputs and control outputs. That’s kind of what Arduino can do, but how does Arduino work? So when we talk about Arduinos we’re really talking about three things: Arduino Hardware, Arduino IDE, and Arduino Code. ARDUINO HARDWARE First, we have the physical component of Arduino which are Arduino boards. There’s a bunch of different types of Arduino boards. When someone says Arduino board, it could mean a number of different boards. A very popular Arduino board is called the Arduino UNO.Arduino UNO boardAll Arduino boards share one thing in common: they all have a microcontroller on them. A microcontroller is basically a really small computer. So when you learn to use Arduino, you’re learning to use a microcontroller. The microcontroller is what enables us to read those different inputs, and control those different outputs. When someone says Arduino board, they’re talking about something physical. It’s a printed circuit board, and it’s got some electrical components on it. ARDUINO SOFTWARE The Arduino is more than just hardware, however, it’s also software. There’s this thing called the Arduino IDE (Integrated Development Environment). This is a software application that you download onto your computer, and then you use it to program the Arduino boards. It’s completely free software, and it’s pretty easy to use. It looks a lot like a text editor. The Arduino IDE is where you write your code that actually gets loaded onto the Arduino board itself.Arduino IDE ARDUINO CODE The third part of this Arduino trifecta is the Arduino code. The code that you write inside the Arduino IDE is ultimately what gets loaded onto the microcontroller that’s on these Arduino boards. The Arduino code that you write is called a sketch. The Arduino code itself is basically a derivative of the C and C++ programming languages, but with some Arduino-specific functions and structure. So if you program an Arduino, you’re basically programming in C and C ++ programming languages. So those are the three components that basically make up what”Arduino is”, and roughly what it does. ***About Us:*** This Arduino tutorial was created by Programming Electronics Academy.
