9. Arduino
ARDUINO IS AN OPEN SOURCE PLATFORM BASE ON EASY TO USE
HARDWARE AND SOFTWARE.
 THE ARDUINO FAMILY CONSISTS OF DIFFERENT TYPES OF DEVELOPMENT
BOARDS, WITH THE MOST COMMON BEING THE ARDUINO UNO.
 AN ARDUINO BOARD CONTAINS A MICROCONTROLLER WHICH CAN BE
PROGRAMED TO SENSE AND CONTROL DEVICES IN THE PHYSICAL WORLD.
 THE MICROCONTROLLER IS ABLE TO INTERACT WITH A LARGE VARIETY OF
COMPONENTS SUCH AS LEDS, MOTORS AND DISPLAYS.

13. Wifi module
 ľ o communicate with the ESP8266 wifi module, micíocontíolleí needs to use set
of A ľ commands.
 Micíocontíolleí communicates with ESP8266-01 wifi module using UARľ having
specified Baud íate (Default 115200).

14. BLUETOOTH MODULE
HC0-05 BLUE
TOOTHMODULE
 HC-05 is a Bluetooth device used foí wiíeless communication with
Bluetooth enabled devices (like smaítphone).
 It communicates with micíocontíolleís using seíial communication
(USARľ).
 Default settings of HC-05 Bluetooth module can be changed using ceítain A ľ
commands.

15. GSM MODULE
 GSM (Global System
for Mobile communication) is a digital mobile
network that is widely used by mobile phone users
in Europe and other parts of the world.
 A GSM module is a specialized type of device
which accepts a SIM card, and operates over
a subscription to a mobile operator, just like a
cell phone or pager.
 The Arduino GSM shield allows an Arduino
board to connect to the internet, send and
receive SMS, and make voice calls using the
GSM library

17. INTRODUCTION
• This is a simple prototype of Smart wheelchair. The wheelchair is multi functioned. One can use this
wheelchair for various purposes.
• This chair can be used as panic alarm. If the person needs instanthelp, he/she can hit the panic alarm button
so that someone can help him/her immediately.
• This wheelchair also has a led light. So, anyone can roam here and there when the surroundings has not
enough light.
• Last but not the least this wheelchair is also automaticallyidentify the obstacles and it makes decision to go
with the obstacle free path.

18. OBJECTIVE
• The objective of this project is to help
physically challenged people. It will basically
very helpful for those who cannot able to
walk.
