Learning Outcomes

3. Lesson 6: Arduino Overview
What is Arduino?

4.  Arduino is an open-source electronics platform
based on easy-to-use hardware and software.
 Arduino boards are able to read inputs - light
on a sensor, a finger on a button, or a Twitter
message - and turn it into an output - activating
a motor, turning on an LED, publishing
something online.

5.  You can tell your board what to do by sending
a set of instructions to the microcontroller on
the board.
 To do so you use the Arduino programming
language (based on Wiring), and the Arduino
Software (IDE), based on Processing.

6. INTRODUCTION
Over the years Arduino has been the
brain of thousands of projects, from
everyday objects to complex scientific
instruments.
A worldwide community of makers -
students, hobbyists, artists,
programmers, and professionals - has
gathered around this opensource
platform, their contributions have added
up to an incredible amount of accessible
knowledge that can be of great help to
novices and experts alike.

7. ORIGIN OF ARDUINO
The Arduino board started
changing to adapt to new
needs and challenges,
differentiating its offer from
simple 8-bit boards to
products for IoT applications,
wearable, 3D printing, and
embedded environments
All Arduino boards are
completely open-source,
empowering users to
build them independently
and eventually adapt them
to their particular needs.
The software, too, is
open-source, and it is
growing through the
contributions of users
worldwide.
Arduino was born at the
Ivrea Interaction Design
Institute as an easy tool
for fast prototyping,
aimed at students
without a background in
electronics and
programming.

8. It runs on Mac,
Windows, and Linux.
Teachers and students
use it to build low cost
scientific instruments,
to prove chemistry and
physics principles, or
to get started with
programming and
robotics.
WHY ARDUINO?
Its simple and
accessible user
experience, Arduino
has been used in
thousands of
different projects and
applications.

9. WHY ARDUINO?
Arduino is a key tool to learn new things.
Anyone - children, hobbyists, artists,
programmers - can start tinkering just
following the step by step instructions of
a kit, or sharing ideas online with other
members of the Arduino community.
Designers and
architects build
interactive
prototypes, musicians
and artists use it for
installations and to
experiment with new
musical instruments.

10. Arduino also simplifies the process of working
with microcontrollers, but it offers some advantage
for teachers, students, and interested amateurs
over other systems:

11. 1) Inexpensive - Arduino
boards are relatively
inexpensive compared to
other microcontroller
platforms. The least
expensive version of the
Arduino module can be
assembled by hand, and
even the pre-assembled
Arduino modules cost
less than Php 2,500.00
Advantages of Arduino

12. 2) Cross-platform -
The Arduino Software
(IDE) runs on
Windows, Macintosh
OSX, and Linux
operating systems.
Most microcontroller
systems are limited
to Windows

13. 3)Simple, clear programming
environment - The Arduino
Software (IDE) is easy-to-use
for beginners, yet flexible
enough for advanced users to
take advantage of as well.
For teachers, it's conveniently
based on the Processing
programming environment, so
students learning to program in
that environment will be
familiar with how the Arduino
IDE works.

14. 4) Open source and extensible
software - The Arduino software is
published as open source tools, available
for extension by experienced
programmers.
The language can be expanded through
C++ libraries, and people wanting to
understand the technical details can
make the leap from Arduino to the AVR C
programming language on which it's
based. Similarly, you can add AVR-C code
directly into your Arduino programs if you
want to.

15. 5) Open source and
extensible hardware -
The plans of the Arduino
boards are published under a
Creative Commons license,
so experienced circuit
designers can make their
own version of the module,
extending it and improving it.
Even relatively inexperienced
users can build the
breadboard version of the
module in order to
understand how it works and
save money.

16. ARDUINO HARDWARE

17. Types of Arduino Boards
 Arduino is a great platform for prototyping projects and
inventions but can be confusing when having to choose the
right board.
 If you’re brand new to this, you might have always thought that
there was just one “Arduino” board and that’s it.
 In reality, there are many variations of the official Arduino
boards and then there are hundreds more from competitors who
offer clones.
 The boards with the name Arduino on them are the official
boards but there are also a lot of really great clones on the
market as well.
 One of the best reasons to buy a clone is the fact they are
generally less expensive than their official counterpart.

18. Arduino UNO
 Arduino UNO is based on an ATmega328P
microcontroller. It is easy to use compared
to other boards, such as the Arduino
Mega board, etc.
 The Arduino UNO includes 6 analog pin
inputs, 14 digital pins, a USB connector, a
power jack, and an ICSP (In-Circuit Serial
