![]() ![]() Typically used to add a reset button to shields which block the one on the board. Bring this line LOW to reset the microcontroller. There are a couple of other pins on the board: Support I2C (TWI) communication using the Wire library (documentation on the Wiring website). ARDUINO DOCS For the full technical documentation. Download the full pinout diagram as PDF here. ![]() It has more or less the same functionality of the Arduino Duemilanove, but in a different package. Additionally, some pins have specialized functionality: The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). Analog pins 6 and 7 cannot be used as digital pins. on Mfg. By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the analogReference() function. The Nano has 8 analog inputs, each of which provide 10 bits of resolution (i.e. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. There is a built-in LED connected to digital pin 13. ![]() These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language. The six pins from the set of digital pins are PWM (Pulse Width Modulation) pins numbered D3, D5, D6, D9, D10, and D11. Provide 8-bit PWM output with the analogWrite() function. See the attachInterrupt() function for details. Each of these analog pins has an inbuilt ADC of resolution of 210 bits (so it will give 1024 values). The function of Analog pins is to read the value of the analog/digital input used in the connection. You can connect up to 8 analog/digital sensors to the board. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. Arduino Nano has eight analog pins numbered from A0 to A7. These pins are connected to the corresponding pins of the FTDI USB-to-TTL Serial chip. Used to receive (RX) and transmit (TX) TTL serial data. In addition, some pins have specialized functions: 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. An Open-Source platform to create digital devices and interactive objects that sense and control physical devices.Īrduino Comparison Chart: Boards & ModulesĮach of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. ![]()
