Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms.

What are the six pins on Arduino Nano?
Arduino Nano Pinout- PWM Pins: If you look closely, you will find the . symbol on digital pin 3,5,6,9,10, and 11. There are six pins from the set of digital pins that are PWM (Pulse Width Modulation) pins. They are numbered as D3, D5, D6, D9, D10, and D11.
How many UART does Arduino Nano have?
Four Boards Communicating with Four Boards Through UART. In this tutorial we will control the built-in LED on four Arduino Nano Every boards, from a main Arduino Nano Every. To do so, we will connect the boards using a wired communication protocol called UART.

Is Arduino Nano 3.3 V or 5V?
The Nano has one 3.3V and two 5V power pins of which one is the VIN pin. With the VIN pin you can supply the Arduino Nano with a voltage between 7V-12V to run the microcontroller on battery for example. Both analog pins A6 and A7 are only analog inputs.

Why is the digital pin 13 a special pin?
The pullup resistors provide enough current to dimly light an LED connected to a pin that has been configured as an input. NOTE: Digital pin 13 is harder to use as a digital input than the other digital pins because it has an LED and resistor attached to it thats soldered to the board on most boards.
Can analog pins be used as digital pins in Arduino?
Yes, the analog pins on the Arduino can be used as digital outputs. You can always use the analog pins for digital writing. digitalRead() works on all pins. It will just round the analog value received and present it to you.
How much power can Arduino Nano supply?
The Arduino Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27).
Which is better Arduino Uno or Nano?
The main difference between these two is the size. Because Arduino Uno size is double to nano board. So Uno boards use more space on the system. The programming of UNO can be done with a USB cable whereas Nano uses the mini USB cable.
Can Arduino use pin 13?
Pins 0-13 of the Arduino Uno serve as digital input/output pins. Pin 13 of the Arduino Uno is connected to the built-in LED. In the Arduino Uno - pins 3,5,6,9,10,11 have PWM capability.
What is pin 13 LED?
The LED on pin 13 is used by the optiboot loader (the one used on UNO): at Arduino boot time (the LED blinks a few times) when uploading a sketch to Arduino.
Are GPIO pins analog or digital?
All 17 of its GPIO pins are digital. They can output high and low levels or read high and low levels. This is great for sensors that provide a digital input to the Pi but not so great if you want to use analogue sensors.
What is the difference between analog and digital pins in Arduino?
The Arduino can input and output analog signals as well as digital signals. An analog signal is one that can take on any number of values, unlike a digital signal which has only two values: HIGH and LOW. pin is the pin number used for the PWM output. value is a number proportional to the duty cycle of the signal.
