What Communication Interfaces are available on Arduino Nano?Īrduino Nano supports three different types of communication interfaces. You can use analogWrite() function for this. All the analog input pins provide a 10-bit resolution ADC feature, which can be read using analogRead() function.Īn important point about Analog Input pins is that they can be configured as Digital IO pins, if required (all analog pins except A6 and A7 can be configured as digital IO).ĭigital IO pins 3, 5, 6, 9, 10 and 11 are capable of producing 8-bit PWM Signals. This is a couple more than Arduino UNO (which only has 6). There are also 8 Analog Input Pins (A0 to A7). The value of the internal pull-up resistor will be in the range of 20KΩ to 50KΩ. An additional feature of the Digital IO pins is the availability of internal pull-up resistor (which is not connected by default). 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.Īll these Digital IO pins are capable of sourcing or sinking 40mA of current. Of the 30 pins available on the Nano board, 22 pins are associated with input and output. What are the Input and Output Pins of Arduino Nano? 2 KB of the Flash Memory is used by the bootloader code.There are three different memories available in ATmega328P. Strictly speaking, this is specific to the MCU used on the Nano Board, which is ATmega328P. What are Different Memories of Arduino Nano? To use, you can provide an unregulated supply in the range of 6V to 20V to VIN pin of the Nano (Pin number 30). The next way is to provide a regulated 5V supply through the 5V pin (Pin number 27).įinally, the Nano has an onboard regulator at the bottom (along with the USB – to – Serial Converter). The first and easy way is using the mini-B type USB Connector. There are a couple of ways in which you can power the Nano board.
