Once the data is being transmitted via FTDI chip and USB connection to the computer, the Rx and Tx Leds on the Arduino Nano are going to blink (however, not in the case of serial communication on 0 pin and 1 pin).
This chip allows to convert USB to a standard serial signal. The Arduino Nano has an FTDI chip (driver) installed on the board. A serial monitor, which is a part of the Arduino software, provides for textual data to be sent to and from the Arduino Board. Serial communication is available on digital pins 0 (RX) and 1 (TX): Rx is used to receive the data and Tx is for transmitting the data. The Arduino Nano can communicate with another Arduino, a computer, or any other microcontroller. What are Arduino Nano facilities for communication? Note: Once the Arduino board is connected to the power source, the board automatically selects the one with the highest voltage. It is a regulated power supply voltage to the board.

If you like the Solder Project Kits, take a look at my full review How to power Arduino Nano?
These digital and analog pins can be assigned with multiple function, but their main one is to be configured as output or input.
Furthermore, Arduino Nano features 14 digital pins and 6 out of them are with PWM (in other words, they are used to generate Pulse Width Modulation). Note: Analogue pins can function as an analogue to digital converter and A4 and A5 pins can be used for I2C communication. The pin is used to provide reference voltage for analog inputs. The pin supports I2C (TWI) communication using the Wire Library. The pin is used to turn on the LED: when the voltage at the pin is high, the LED is on, when it is low, it’s off. In-built LED is connected to the digital pin 13. The signal can be generated with the analog function.ġ0 (SS), 11 (MOSI), 12 (MISO) and 13 (SCK) The pins are used to trigger an interrupt on a low value or a change in value, a rising or falling edge.Įach of these pins is used to provide a Pulse Width Modulation (PWM) signal of 8-bit resolution. The pins are used to receive (Rx) and transmit (Tx) TTL serial data. The pins are used to measure analog voltage in the range of 0-5VĬan be used as input or output pins. The pin is used to reset the microcontroller. GND: Ground pins: any of which can be used to ground your circuit Vin: The input voltage to Arduino board when it is using an external power sourceĥV: This pin outputs a regulated 5V from the regulator on the board.ģ.3V: Can be used to power other external components which use a 3.3V connection Specific functions are assigned to each of the pin, as shown in the table below. Note that analog pins 6 and 7 cannot be used as digital pins.Īrduino Nano Pinout contains 14 digital pins, 8 analog pins, 2 reset pins and 6 power pins. analogue input can give 1024 different values). The Arduino Nano features 8 analog inputs, and either of which can provide 10 bits of resolution (e.i. Moreover, each pin can provide or receive a current of 40 mA maximum and operate at 5V voltage as maximum. Arduino Nanoĭiscover the Best Starter Kits with Breadboard Arduino Nano Input and OutputĪrduino Nano has 14 digital pins and each of them can be used both ways: as input and output. Let’s get started with the Arduino Nano specifications, or general technical characteristics. What are Arduino Nano facilities for communication?.
