#5 Analog Pins of Arduino Uno.

This is 5th post on Arduino tutorial.

Analog Pins :-

  • Analog Pins are used for taking a input from senors, which are analog in nature.
  • Analog pins can take values that are intermediate, unlike digital pins which just understand HIGH and LOW.
  • The Atmega controllers used for the Arduino contain an onboard 6 channel analog-to-digital (A/D) converter. The converter has 10 bit resolution, returning integers from 0 to 1023. [skip this point if not understood].
  • While the main function of the analog pins for most Arduino users is to read analog sensors, the analog pins also have all the functionality of general purpose input/output (GPIO) pins (the same as digital pins 0 - 13).
Analog Pins are used a lot because most of the sensors/transducers are analog in nature. Analog pins on Arduino Uno are named as A0 to A5 i.e. we have six analog pins !

Since now we have our Arduino IDE installed, we are pretty comfortable with the board and all the pins on the board, yes its time that we do something with our board!

Arduino is a really powerful tool if you are creative and can do a good programming, no need to worry just follow the tutorials and I will make sure you learn everything :-)
