  INTRODUCING YOU TO ARDUINO

  Hey baba who designedme 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 .

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

   1 Arduinocan 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

   (11) MICROCONTROLLER: itsjust 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..

  (16)AREF  stands forAnalog 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.

  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

  To create ananalog signal, the microcontroller uses a technique called PWM. By varying the duty cycle, we can mimic an “average” analog voltage. PULSE WIDTH MODULATION

  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
