How to build Arduino projects?


Arduino is an open-source platform for hardware and software. They take inputs from sensors and perform operations as per the program fed into the Arduino to give relevant outputs. It is easy to use, a flexible tool that can be used to perform a variety of functions. They are widely used across various domains for different applications. Engineering students use it to implement electronics projects and learn more about it.

It works as the microcontroller which controls the entire application using the program embedded into it. Building Arduino projects might seem a bit intimidating but it’s really easy. In this article, we will also cover some of the exciting Arduino projects which will help you understand the working of Arduinos better.

Things to know before building an Arduino project

Things to know before building an Arduino project

  1. Sketch Writing- The codes written in the Arduino interface are called a sketch. These sketches are usually written in C and uploaded to the Arduino board. So, if you learn how to write sketches, you’ll be learning about the fundamentals of C.
  2. Arduino Libraries- These libraries are full of tools that will simplify your task. They can reduce the size of your sketches from thousands of lines to a few hundred if you’re aware of those libraries.
  3. Basic ports- You should learn about the basic ports and serial and parallel communication. If you know about the serial and parallel pins and how they operate, it will come in handy when you’re implementing projects.
  4. Memory limit- You should be aware of the memory limit to keeping a check on the codes you write. Eventually, you will hit the maximum limit, which will help you optimize the code to make sure the code fits in the limit.

What are the types of Arduino?

Different types of Arduino boards are available in the market these days. These boards differ in their specifications and the purpose for which they are used. Some of the most popular ones are:

  1. Arduino Uno (R3)- This is a good choice for a beginner with 14 digital I/O pins, a power jack, a USB connection and more. It can be simply connected to a computer and used as per the need.
  2. Lilypad Arduino- This type of Arduino is used for wearable projects like health monitoring glove, smart band, etc. It is designed to be sewn into clothes using conductive thread. They consist of I/O power, sensor boards, etc and It is washable.
  3. Red board Arduino- This board can be programmed and controlled using a Mini-B USB cable using Arduino IDE. It is very simple to use.
  4. Arduino Mega (R3)- This board is very similar to Arduino Uno except that it has more number of pins which makes the board more useful for projects requiring more connections.
  5. Arduino Leonard- Being the first development board of Arduino, Leonard is very cheap and easy to use. It uses one microcontroller with USB with easily obtainable program libraries.

How to build Arduino projects?

Before starting to build a project you first need to gain basic knowledge about the project or technology that you are going to work. You should have well-versed knowledge about each and every component and also should troubleshoot it if anything is not working properly.

Research about the components that you are going to use in your project and select the components properly some components will not work with certain types of Arduino board.

Select the components which can be used for further projects also so that your project cost will be reduced.
