3. My Seminar is about “Home automation using
Arduino”.
Control most of your devices at home using your Laptop
or phone.
Get feedback about the status of your home via Internet.
Provide an easily and comfortable way to control your
home devices from any place.
Introduction
4. People usually are outside the home for many reasons
like travelling and they want to control some devices
from a far distance. Examples:
i. Want to fill the water tank.
ii. Want to turn off the light and electronic devices at
rooms.
iii. Get feedback about the temperature.
iv. If somebody at your home.
v. Total control on your home.

5. Home Automation
Home automation gives you access to control devices in your home
from a laptop , mobile device, anywhere in the world.
Home automation more accurately describes homes in which nearly
everything -- lights, appliances, electrical outlets, heating and
cooling systems -- are hooked up to a remotely controllable
network
6. Arduino Uno
The main piece in technology used is an arduino
ATmega328 kit attached by GPRS/GSM Shield
Technology used
7. Microcontroller ATmega328
Operating Voltage 5V
Input Voltage (recommended) 7-12V
Input Voltage (limits) 6-20V
Digital I/O Pins 14 (of which 6 provide PWM output)
Analog Input Pins 6
DC Current per I/O Pin 40 mA
DC Current for 3.3V Pin 50 mA
Flash Memory
32 KB (ATmega328) of which 0.5 KB used by
bootloader
SRAM 2 KB (ATmega328)
EEPROM 1 KB (ATmega328)
Clock Speed 16 MHz
8. GSM Shield
The Arduino GSM Shield connects
our Arduino to the network. Plug in
a SIM card from an operator
offering GPRS coverage and also
you can also make/receive voice
calls and send/receive SMS
messages
9. There are 5 Pins in a relay.
Two pins 1 and 2 are two
ends of a coil that are kept
inside the relay. The coil is
wound on a small rod that
gets magnetized whenever
current passes through it.

12. Language:-
Arduino programs are written in C/C++, although users only need define two functions
to make a runnable program:
setup() – a function run once at the start of a program that can initialize settings
loop() – a function called repeatedly until the board powers off
#define LED_PIN 13
void setup ()
{
pinMode (LED_PIN, OUTPUT); // enable pin 13 for digital output
}
void loop ()
{
digitalWrite (LED_PIN, HIGH); // turn on the LED
delay (1000); // wait one second (1000 milliseconds)
digitalWrite (LED_PIN, LOW); // turn off the LED
delay (1000); // wait one second
}
