THIS PPT MAKES ANYONE AWARE ABOUT ARDUINO AND MAKES STRONG AT BASICS.ALSO CONTAIN DIFFERENCE BETWEEN MICRO PROCESSOR AND MICRO CONTROLLER

1. WELCOME TO ARDUINO WORKSHOP
- An Early Exploration
20,21,22 Dec2k19

2. INTRODUCING
YOU TO
ARDUINO

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?

5. Microprocessor
Microcontroller

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.

10. Arduino uno

11. There are many versions of Arduino board.versions differ
by size,microcontroller,etc
DIFFERENT FLAVOURS!!!

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
