Oct 31, 2020 · Each of the 14 digital pins on the Nano pinout can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. Other than the digital input and output functions, the digital pins have some additional functionality as well.

Sep 18, 2024 · What are the Input and Output Pins of Arduino Nano? Of the 30 pins available on the Nano board, 22 pins are associated with input and output. In that 14 pins (D0 to D13) are true digital IO pins, which can be configured as per you application using pinMode (), digitalWrite () and digitalRead () functions.

Mar 26, 2024 · Arduino Nano has a total of 36 pins. Out of these 8 are analog input pins and 14 digital input/output pins (of which 6 can be used as PWM outputs). Nano has a 16 MHz SMD crystal resonator, a mini USB-B port, an ICSP header, 3 RESET pins, and, a RESET button.

Jul 17, 2021 · +5V Pin: If you have a regulated +5V supply then you can directly provide this o the +5V pin of the Arduino. Input/output: There are total 14 digital Pins and 8 Analog pins on your Nano board.

Arduino Nano has Power pins, analog, and 14 digital pins. We used the Analog and digital pins for communication with different electronic components and sensors. If we look at one side of the board, a six-pin header is located for ICSP (In-circuit series programming).

Feb 27, 2021 · Arduino Nano has 14 digital pins and each of them can be used both ways: as input and output. Moreover, each pin can provide or receive a current of 40 mA maximum and operate at 5V voltage as maximum.

Feb 26, 2025 · Overview of Arduino Nano Pins. The Nano features 30 pins, categorized as follows: 14 Digital I/O Pins (D0–D13): Can be used for digital input/output, PWM, and interrupts. 8 Analog Input Pins (A0–A7): Six (A0–A5) double as digital pins (14–19), while A6–A7 are analog-only. Power Pins: 5V, 3.3V, Vin, GND, AREF, and RESET.

Feb 16, 2025 · When a digital pin is set as an input, it is used to read the state of an external component, like a switch or a sensor. Whether the signal received at the pin is counted as HIGH (1) or LOW (0) is determined by the voltage level. When a pin is configured as an output, it can provide a HIGH (5V) or LOW (0V) to components connected to it.

Jan 27, 2025 · The Arduino Nano features 8 analog input pins (A0–A7), which can read signals from analog sensors and convert them into digital values. Input Range: These pins can read values between 0 and 1023, corresponding to a voltage range of 0V to 5V.

Understanding the pin mapping diagram will allow you to identify the specific pins that can be used for digital input and output and determine their corresponding functionalities. In addition to digital input and output, the Arduino Nano also provides analog input and output capabilities.
