  3. //arduino overview
  4. Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike.

  6. //pin configuration
  7. Vin: This is the input voltage pin of the Arduino board used to provide input supply from an external power source.
  8.  
  9. 5V: This pin of the Arduino board is used as a regulated power supply voltage and it is used to give supply to the board as well as onboard components.
  10.  
  11. 3.3V: This pin of the board is used to provide a supply of 3.3V which is generated from a voltage regulator on the board
  12.  
  13. GND: This pin of the board is used to ground the Arduino board.
  14.  
  15. Reset: This pin of the board is used to reset the microcontroller. It is used to Resets the microcontroller.
  16.  
  17. Analog Pins: The pins A0 to A5 are used as an analog input and it is in the range of 0-5V.
  18.  
  19. Digital Pins: The pins 0 to 13 are used as a digital input or output for the Arduino board.
  20.  
  21. Serial Pins: These pins are also known as a UART pin. It is used for communication between the Arduino board and a computer or other devices. The transmitter pin number 1 and receiver pin number 0 is used to transmit and receive the data resp.
  22.  
  23. External Interrupt Pins: This pin of the Arduino board is used to produce the External interrupt and it is done by pin numbers 2 and 3.
  24.  
  25. PWM Pins: This pins of the board is used to convert the digital signal into an analog by varying the width of the Pulse. The pin numbers 3,5,6,9,10 and 11 are used as a PWM pin.
  26.  
  27. SPI Pins: This is the Serial Peripheral Interface pin, it is used to maintain SPI communication with the help of the SPI library. SPI pins include:
  28.  
  29. SS: Pin number 10 is used as a Slave Select
  30. MOSI: Pin number 11 is used as a Master Out Slave In
  31. MISO: Pin number 12 is used as a Master In Slave Out
  32. SCK: Pin number 13 is used as a Serial Clock
  33. LED Pin: The board has an inbuilt LED using digital pin-13. The LED glows only when the digital pin becomes high.
  34.  
  35. AREF Pin: This is an analog reference pin of the Arduino board. It is used to provide a reference voltage from an external power supply.
