DESIGN INNOVATION CENTRE

Free and Open-Source Software (FOSS)
 Free and open-source software (FOSS) allows users and programmers to edit,
modify or reuse the software's source code. This gives developers the
opportunity to improve program functionality by modifying it.
 The term “free” indicates that the software does not have constraints on
copyrights. The term “open source” indicates the software is in its project
form, enabling easy software development from expert developers
collaborating worldwide without any need for reverse engineering.
 Some examples of FOSS include: Linux Kernel, Ubuntu, Nextcloud, Google
Chrome OS, Android OS, BSD, GIMP, Blender, OpenOffice, Chrome
Browser, Eclipse, etc.

Why Was Arduino Developed?
 Physical Computing – using components that can interact with people and
with the world around us
 The Arduino was originally developed for artists and designers to prototype
interactive displays at Italy by Massimo Banzi and David Cuartielles in
2005.
 Developed for non-scientists
 Minimalist programming
 “Forgiving” circuitry that can handle a wide variety of wiring errors

What is Arduino Not?
 It is not a chip (IC)
 It is not a board (PCB)
 It is not a company or a manufacturer
 It is not a programming language
 It is not a computer architecture
(although it involves all of these things...)
Official Definition: Arduino is an open-source electronics prototyping
platform based on flexible, easy-to-use hardware and software. It's
intended for artists, designers, hobbyists, and anyone interested in
creating interactive objects or environments.

So, What is Arduino?
 It’s a movement, not a microcontroller
 Founded by Massimo Banzi and David Cuartielles in 2005 based on
“Wiring Platform”, which dates to 2003
 Open-source hardware platform
 Open source development environment
 Easy-to learn language and
libraries (based on Wiring
language)
 Integrated development
environment (based on
Processing programming
environment)
 Available for Windows /
Mac / Linux

Why Arduino?
 For whatever reason, Arduino microcontrollers have
become the de facto standard
 Strives for the balance between ease of use and
usefulness
1. Programming languages seen as major
obstacle
2. Arduino C is a greatly simplified version of
C++
 It is an open-source project, software/hardware is
extremely accessible and very flexible to be
customized and extended
 Arduino is backed up by a growing online
community, lots of source code is already available
and we can share and post our examples for others to
use, too!
 It is inexpensive and comes with free authoring
software

Electricity Electronics Basic Concepts
 Voltage (V)
Voltage, also called electromotive force, is the potential difference in
charge between two points in an electrical field.
It is measured in Volt (V).
 Current (I)
Current is the rate at which electric charge flows past a point in a circuit. In
other words, current is the rate of flow of electric charge.
It is measured in Ampere (A).
 Resistance (R)
Resistance is a measure of the
opposition to current flow in an
electrical circuit.
It is measured in ohms, symbolized
by the Greek letter omega (Ω).

Alternating Current & Direct Current
 Alternating Current (AC)
Alternating current is defined as the flow of charge that changes direction
periodically. The result obtained will be, the voltage level also reverses along with
the current. Basically, AC is used to deliver power to industries, houses, office
buildings, etc.
 Direct current (DC)
Direct current is the movement of electric charge carriers, i.e. electrons in a
unidirectional flow. In DC, the intensity of the current will vary along with time,
but the direction of movement stays the same in all time. Here DC is referred to a
voltage whose polarity never reverses. DC power is widely used in low voltage
applications such as charging batteries, automotive applications, aircraft
applications.

Ohm’s Law
 The relationship between Voltage, Current and Resistance in
any DC electrical circuit was firstly discovered by the German
physicist Georg Ohm.
 Ohm's law states that the current through a conductor between
two points is directly proportional to the voltage across the two
points
The Power TriangleThe Ohm’s Law Triangle

Current Flow , Voltage Flow & Resistance Analogies
Water = Charge
Pressure = Voltage (V)
Flow = Current (I)
Size of the Pipe = Resistance (R)

Circuit
 An electronic circuit is composed of individual electronic
components, such as resistors, transistors, capacitors, inductors
and diodes, connected by conductive wires or traces through
which electric current can flow. To be referred to as electronic,
rather than electrical, generally at least one active component
must be present.
 The word “circuit” is derived from the circle. An Electrical
Circuit must have a continuous loop from Power (Vcc) to
Ground (GND).

Electronic Components
 Active Components
Those devices or components which
required external source to their
operation is called Active Components.
For Example: Diode, Transistors,
SCR, ICs, etc.
 Passive Components
Those devices or components which do
not required external source to their
operation is called Passive
Components.
For Example: Resistor, Capacitor,
Inductor, LDR, etc.

Resistor
 A resistor is a passive two-terminal electrical component that
implements electrical resistance as a circuit element.
 In electronic circuits, resistors are used to reduce current flow,
adjust signal levels, to divide voltages, bias active elements, and
terminate transmission lines, among other uses.

Breadboard
 A breadboard is a solder-less device for
temporary prototype with electronics and test
circuit designs.
 Because the solder-less breadboard does not
require soldering, it is reusable.
 This makes it easy to use for creating
temporary prototypes and experimenting with
circuit design.

Analog & Digital Signals
What is analog ?
 It is continuous range of voltage
values (not just 0 or 5V)
 Analog has many (infinite) values
Why convert to digital ?
 Because our microcontroller only
understands digital.
 Digital has two values: on and off

medical equipment, household appliances, vending machines and toys, as well
as mobile devices, are possible locations for an embedded system.

Boot Loader
What's a boot loader?
Microcontrollers are usually programmed through
a programmer unless you have a piece of firmware in your
microcontroller that allows installing new firmware without
the need of an external programmer. This is called a boot
loader.

 Speed = 1-100 MHz (clock/device
limited)
 Four-wire bus: SCLK, MOSI, MISO &
SS
 Multiple slaves can share same bus (but
each needs a dedicated SS, slave select)

PWM & Duty Cycle
 Pulse-width modulation (PWM) is used for
controlling the amplitude of digital signals in
order to control devices and applications
requiring power or electricity.
 Duty cycle = Pulse Width / Wave Period

Setting Up of Arduino IDE
 The computer
communicates
to the Arduino
microcontroller
via a serial port
through a USB-
Serial adapter.
 Check to make
sure that the
drivers are
properly
installed.
Step 1
Settings: Tools  Board  Arduino Uno
Step 2
Settings: Tools  Settings: Tools  Serial Port  COM#(Arduino Uno)

Arduino Sketch Structure
void setup()
Will be executed only when
the program begins (or reset
button is pressed)
void loop()
Will be executed repeatedly

Arduino Program Development
 Based on C++ without 80% of
the instructions.
 A handful of new commands.
 Programs are called 'sketches'.
 Sketches need two functions:
 void setup( )
 void loop( )
 setup( ) runs first and once.
 loop( ) runs over and over,
until power is lost or a new
sketch is loaded.

Important Functions
 pinMode(pin, mode)
Designates the specified pin for input or output
 digitalWrite(pin, value)
Sends a voltage level to the designated pin
 digitalRead(pin)
Reads the current voltage level from the designated pin
 analogWrite(pin, value)
Sends analog voltage of the range 0 to 1023 to the designated pin
 digitalRead(pin)
Reads the current analog voltage of the range 0 to 1023 from the designated
pin
 delay(delaytime)
pauses the execution of the program for the given amount of time
 Serial Commands
print(), println(), write(), read(), begin(), end(), find()

Variables
 A variable is a way of naming and storing a value for later use by the
program, such as data from a sensor or an intermediate value used in a
calculation.
Declaration
 Before they are used, all variables have to be declared. Declaring a variable
means defining its type, and optionally, setting an initial value (initializing
the variable). Variables do not have to be initialized (assigned a value)
when they are declared, but it is often useful.
8 bits 16 bits 32 bits
byte
char
int
unsigned int
long
unsigned long
float

Conditions
If Statement: If a certain condition is true, the
set of statements enclosed in curly braces are
executed. If the condition is false, then the set of
statements are skipped during the execution.
if(some variable ?? state){
}
If Else Statement makes an “either-or decision.
The if statements checks a condition. If it is true,
it executes a set of statements; if the condition is
not true, it executes other set of statements under
else.
if (some variable ?? state){
}
else{
}
For Loop: If you want to repeatedly execute a set
of statements for a specific number of times, then
you can use a for loop.
for(initialization; condition; expression){
}
While Loop executes a set of statements until the
expression inside the parentheses is false
while (some variable ?? value){
}
Do While Loop executes a set of statements once
and repeatedly execute the set if a certain condition
is true.
do{
} while (some variable ?? value);
Switch Case Statement allows to execute one
code block among many alternatives.
switch (expression)
{
case 1:
// statements
break;
case 2:
// statements
break;
default: // default statements
}

Basic IDE Code

LED
Applications

Code & Explanation
/*LED Blink Experiment */
int led =9; // LED anode is connected to Arduino Pin 9
void setup(){
pinMode(led,OUTPUT); // Initialize the digital pin as an output
}
// The loop routine runs over and over again forever:
void loop(){
digitalWrite(led,HIGH); // turn the LED on by making voltage HIGH
delay(1000); // wait for a second
digitalWrite(led,LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

Activity 2 : Potentiometer
Potentiometer
 A potentiometer is a three-terminal resistor with a sliding or rotating
contact that forms an adjustable voltage divider.
 If only two terminals are used, one end and the wiper, it acts as a variable
resistor or rheostat.
Applications:
 Controllers
 Audio Systems
 Measuring Devices
 Tuners & Calibrators

Code & Explanation
/* Program to control LED by varying the pulse width */
int potPin = 2; // select input pin A2 for the pot
int ledPin = 13; // select output pin 13 for the LED
int val = 0; // variable to store pot voltage
void setup() {
pinMode(ledPin, OUTPUT); // declare ledPin13 as an
OUTPUT
}
void loop() {
val = analogRead(potPin); // read pot voltage as integer
digitalWrite(ledPin, HIGH); // turn the ledPin on
delay(val); // stop the program for some time
digitalWrite(ledPin, LOW); // turn the ledPin off
delay(val); // stop the program for some time
}

Activity 3 : Push Button Switch
Switch
 A switch is an electrical component that can "make" or "break" an
electrical circuit, interrupting the current or diverting it from one conductor
to another.
 The mechanism of a switch removes or restores the conducting path in a
circuit when it is operated.
 It may be operated manually, for example, a light switch or a keyboard
button, may be operated by a moving object such as a door, or may be
operated by some sensing element for pressure, temperature or flow.

Code & Explanation
// Program for Push Button with LED
// set pin numbers:
const int buttonPin = 7; // Pushbutton pin
const int ledPin = 9; // LED pin
// variables will change:
int buttonState = 0;
// variable reads pushbutton status
void setup() {
// initialize the LED pin as an output
pinMode(buttonPin, INPUT);
// initialize the pushbutton pin as an input
}
void loop()
{
buttonState =
digitalRead(buttonPin);
// read the state of the pushbutton value
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
// check if the pushbutton is pressed
digitalWrite(ledPin, HIGH);
// turn LED on
}
else
{
digitalWrite(ledPin, LOW); // turn
LED off
}
}

Activity 3.1 : Interrupt
Interrupt Introduction
 An interrupt, in microcontroller context, is a signal that temporarily stops what
the CPU is currently working at.
 A typical Arduino sketch consists of setup() and loop() functions. When a
sketch is executed, the top most lines are run first. So logically
the setup() function is run before the loop() function. Although it’s far more
common to have headers for libraries above setup() which are of course catered
first by the compiler. The loop() function is an endless loop so there is no way
to exit it.
 If we will now use interrupts, we add a third function named isr(). ISR is short
for Interrupt Service Routine. This is where the program jumps to whenever
there is an interrupt.
 When does the program jump to isr()?
 Arduino Uno Digital Pins: 2 & 3 usable for interrupts
 attachInterrupt(digitalPinToInterrupt(interruptPin), isr, CHANGE);
void setup(){
}
void loop(){
}
void isr(){
}

Code & Explanation
//Program for Arduino Interrupt
//Make connections as per the code ! 
const byte ledPin = 13;
const byte interruptPin = 2;
volatile byte state = LOW;
void setup() {
pinMode(interruptPin, INPUT_PULLUP);
attachInterrupt(digitalPinToInterrupt(interruptPin), blink, CHANGE); //Interrupt
}
void loop() {
digitalWrite(ledPin, state);
}
void blink() { //ISR
state = !state;
}

Activity 4 : Controlling an RGB LED
RGB LED
 RGB LED means Red, Blue and Green Light Emitting Diode.
 By configuring the intensity of each LED, other colours can be produced.
There are two kinds of RGB LEDs: common anode LED and common
cathode LED.
Applications:
 Interior Lighting
 Signs & Displays
 Designer Decorations

Code & Explanation
/* Program to control RGB
LED */
int redPin = 11;
int greenPin = 10;
int bluePin = 9;
void setup()
{
pinMode(redPin, OUTPUT);
pinMode(greenPin,
OUTPUT);
pinMode(bluePin, OUTPUT);
}
void loop()
{
setColor(255, 0, 0); // red
delay(1000);
setColor(0, 255, 0); //

green, int blue)
{
analogWrite(redPin, red);
analogWrite(greenPin,
green);
analogWrite(bluePin,
blue);
}

Activity 5 : Piezo Buzzer
Piezo Buzzer
 A buzzer or beeper is an audio signalling device, which may be mechanical,
electromechanical, or piezoelectric (piezo for short).
 Typical uses of buzzers and beepers include alarm devices, timers, and confirmation
of user input such as a mouse click or keystroke.
 Whenever an electric potential is applied across a piezoelectric material, a pressure
variation is generated. A piezo buzzer consists of piezo crystals in between two
conductors. When a potential difference is applied across these crystals, they push
one conductor and pull the other conductor by their internal property. The
continuous pull and push action generates a sharp sound wave.

Code & Explanation
//A sketch to demonstrate the tone()
function
//Specify digital pin on the Arduino that
the positive lead of piezo buzzer is
attached.
int piezoPin = 9;
void setup() {
}//close setup
void loop() {
/*Tone needs 2 arguments, but can
take three
1) Pin#
2) Frequency - this is in hertz (cycles
per second) which determines the pitch
of the noise made
3) Duration - how long teh tone
plays */
tone(piezoPin, 1000, 500);
//tone(piezoPin, 1000, 500);
//delay(1000);
}

Activity 6 : LCD Display
LCD
 LCD (Liquid Crystal Display) is a type of flat panel display which uses liquid
crystals in its primary form of operation.
 LCDs have a large and varying set of use cases for consumers and businesses, as
they can be commonly found in smartphones, televisions, computer monitors and
instrument panels.
I2C Bus
 I2C stands for Inter Integrated Circuit
 A I2C bus is a bidirectional two-wired
serial bus which is used to transport the data
between integrated circuits.

Code & Explanation
//Program for LCD Display with I2C
Bus
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

//If key is pressed, this key is stored in
'keypressed' variable’
//If key is not equal to 'NO_KEY', then this
key is printed out
void loop() //main program
{
char keypressed = kpd.getKey();
if (keypressed != NO_KEY)
