Description

Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328. It has more or less the same functionality as the Arduino Duemilanove but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one. It contains 30 male I/O headers, configured in a DIP30 style. Its pinout contains 14 digital pins, 8 analog Pins, 2 Reset Pins & 6 Power Pins. It is programmed using Arduino IDE, which can be downloaded from Arduino Official site.

Arduino Nano is simply a smaller version of Arduino UNO, thus both have almost the same functionalities. It comes with an operating voltage of 5V, however, the input voltage can vary from 7 to 12V. Arduino Nano’s maximum current rating is 40mA, so the load attached to its pins shouldn’t draw current more than that. Each of these Digital & Analog Pins is assigned with multiple functions but their main function is to be configured as Input/Output. Arduino Pins are acted as Input Pins when they are interfaced with sensors, but if you are driving some load then we need to use them as an Output Pin.
