49+ Arduino Nano Number Of Digital Pins
Photos. The pins work with 5v voltage as. I suspect the digital pin count includes the tx and rx and analog pins, which are also usable as digital pins (except for a6 and a7 which are analog only, so the correct number of pins would be 20, not 22).
Introduction To Arduino Nano The Engineering Projects from www.theengineeringprojects.com
The digital pins can be used to interface sensors by using them as input pins or drive loads by using them as output pins. While the title of this document refers to digital pins, it is important to note that vast majority of arduino (atmega) analog pins, may be configured, and used. click the image to enlarge it.
There are pins with secondary functions on the table below.
The arduino nano has a number of facilities for communicating with a computer, another arduino, or other microcontrollers. An ftdi ft232rl on the board channels this serial. The nano is inbuilt with the atmega328p microcontroller as mentioned earlier, arduino nano has 14 digital i/o pins that can be used either as digital input or output. Incorrect digital pin count for nano.
