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). Additionally, some pins have specialized functionality: Analog pins 6 and 7 cannot be used as digital pins. 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. Provide 8-bit PWM output with the analogWrite() function. See the attachInterrupt() function for details. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.

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. Input and OutputĮach of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.
The ATmega328 has 2 KB of SRAM and 1 KB of EEPROM. The ATmega328 has 32 KB, (also with 2 KB used for the bootloader. The power source is automatically selected to the highest voltage source. 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). Is it able to handle serial communication? And is there somewhere a store where I can get it cheap? I think more than 20$ for a shield is a bit too much.The Arduino Nano is open-source hardware! You can build your own board using the following files: EAGLE FILES IN. It's a shield, but I'm not sure if it would fit my needs.
#Arduino nano usb 2.0 serial for android#
I stumbled across the USBHost for Android Nano. Would it be possible to create a USB Host with this library, that can communicate via a virtual serial connection? But I've read a few things about that 'V-USB' library, but did not understand very much. I found out, that I would not be able to use the 'usual' usb port of the nano. Since I don't have much knowledge about USB communication, I would like to know the following, before I start digging deeper: I was already able to 'talk' to it using a Raspberry Pi. That's because the other device is a vacuum cleaner: Neato XV-25 with a mini usb jack. My project is actually quite simple: I just want to write out data over a serial connection via USB, the problem: My Arduino Nano has to run as USB Host. I'm pretty new to microcontrollers and Arduino and since I can't find any satisfying information on my problem, I hope that you might answer them:
