Arduino Uno R3 Basic – Tutorial 1

Hello Guys !!!

Nowadays, the technology gets improvised every single second at the lighting speed. As a part of technology, I am going to explain basic fundamental of Arduino Uno R3. In this tutorial, we will discuss about some basic requirement of hardware and software.

Before starting Arduino, we’ll need a few things that we need to know about. Let’s take a look at this. Hardware and software are needed when people say how to set up an Audino UnoR3.

Let’s first of all we are going to discuss about Hardware of Arduino Uno R3.

In market many types of Arduino boards available, but we are going to discuss about most popular one – Arduino uno R3. Its board official price is Rs.1800 to Rs. 2100 and clone board of Arduino uno R3 price is Rs. 350 to Rs. 750.

We can connect many component with Arduino uno R3 like motors, LED’s , buzzer, ldr etc.


Arduino Uno board is powered from your computer’s USB port when you connect it to your PC to upload a program.When the
Arduino is not linked to your PC, you can run it independently by connecting a 9-volt AC adapter or 9-volt battery pack with a 2.1 mm jack,
with the center pin connected to the positive wire. Simply insert the jack into the power socket of the Arduino.


A breadboard called construction base of circuit for electronics prototyping. We will discuss many project in future tutorials. All project will be done on BREADBOARD. It is made up of plastic with pre drilled holes. Its comes with different size.

Jumper Wires :-

These Jumper wires are solid-core wires come with a molded plastic holder on each end that makes it easier to insert and remove the wires. You can use your own wire instead if these.

As shown in figure jumper wire connected from Arduino I/O to Breadboard points.

Programming the Arduino UNO R3
1To make our projects do what we want, we need to write programs
that give the Arduino instructions. We do so using a tool called the
Arduino integrated development environment (IDE).
2The Arduino
IDE is free to download from, and will run
on Windows, OS X, and Linux. It enables you to write computer
programs (a set of step-by-step instructions, known as sketches in
the Arduino world) that you then upload to the Arduino using a USB
3Your Arduino Uno R3 will carry out the instructions based on its interaction with the outside world.

The IDE Interface

The IDE is divided intodifferent part :-

1. Toolbar at the top, with buttons for the
most commonly used functions.

2. The code or sketch window in the
center,where you’ll write or view your programs.

3. The Serial Output window at the bottom.

4. The Serial Output window displays communication messages between your PC and the Arduino UNO R3.
