3. Hey baba who
designed me and
why I was named
arduino
The
name Arduino comes
from a bar in Ivrea,
Italy, where some of
the founders of the
project used to meet.
The bar
was named after
Arduin of Ivrea,
You stupid.you
were designed
by Massimo
Banji .
4. After 3-
days
This is so
simple,
thrilling and
interesting.
What is Arduino?why
should I know about this?
6. IT IS USED IN APPLICATION WHERE TASK IS NOT
PREDEFINED.
MULTI-FUNCTIONAL ENVIRONMENT
eg:-Our personal computer
GAMING
WEB BROWSING
MEDIA STREAMING
MICROPROCESSOR
7. IT IS DESIGNED TO PERFORM SPECIFIC TASKS/ TASK IS PREEFINED.
MICRO CONTROLLER
INPUT
MICROCONTROLLE

11. There are many versions of Arduino board.versions differ
by size,microcontroller,etc
DIFFERENT FLAVOURS!!!
12.
13. 1 Arduino can be powered using USB cable .
2 Arduino can be powered directly from the AC mains power supply by through Barrel Jack.
(3)VOLTAGE REGULATOR:
Voltage regulator controls the voltage supplied to Arduino and stabilize the DC voltage(7-
12).
4 CRYSTAL OSCILLATOR:The crystal oscillator deals with time issues.(16Mhz)
5,14:-Arduino reset:You can reset your Arduino board by two ways.
(6,7,8,9)Pins (3.3, 5, GND, Vin).
ANALOG PINS:
The Arduino UNO has five analog input pins (A0 - A5). These pins can read the signal from
an analog sensor like humidity ,temperature sensor and converts to digital value.
BASIC PIN CONFIGURATION
14. (11) MICROCONTROLLER:
its just like brain to Arduino board.
(12) ICSP stands for In-Circuit Serial Programming.
(13)POWER LED INDICATOR
(14) TX AND RX LEDs:
TX (transmit) and RX (receive).
0 and 1, to indicate the pins responsible for serial communication.
TX led flashes when sending serial data. The speed of flashing relies
on baud rate.
RX flashes during the receiving process.
(15)Digital I / O
14 digital I/O pins
6 PWM (Pulse Width Modulation)pins(3,5,6,9,10,11) labeled “~” .
Cont..
15. (16)AREF
stands for Analog Reference. It is sometimes, used to set an external
reference voltage (between 0 and 5 Volts) as the upper limit for the
analog input pins.
16. Concepts: Analog vs. Digital
Microcontrollers are digital devices – ON or OFF. Also
called – discrete.
analog signals are anything that can be a full range of
values. What are some examples? More on this later…
5 V
0 V
5 V
0 V
17. To create an analog signal, the microcontroller uses a technique called PWM. By varying the duty cycle, we
can mimic an “average” analog voltage.
PULSE WIDTH MODULATION
18. analogWrite(pin, val);
pin – refers to the OUTPUT pin (limited to
pins 3, 5, 6, 9, 10, 11.) – denoted by a ~
symbol
val – 8 bit value (0 – 255).
0 => 0V | 255 => 5V
