Description: # Arduino-Python3 Command API
        
        This API is forked from the original [Python Arduino Command API](https://github.com/thearn/Python-Arduino-Command-API) to add support for Python 3.
        
        The Arduino-Python3 Command API is a lightweight Python library for
        communicating with [Arduino microcontroller boards](http://www.arduino.cc/) from a connected computer using
        standard serial IO, either over a physical wire
        or wirelessly. It is written using a custom protocol, similar to [Firmata](http://firmata.org/wiki/Main_Page).
        
        This allows a user to quickly prototype programs for Arduino using Python code, or to
        simply read/control/troubleshoot/experiment
        with hardware connected to an Arduino board without ever having to recompile and reload sketches to the board itself.
        
        Method names within the Arduino-Python3 Command API are designed to be as close
        as possible to their Arduino programming language counterparts
        
        ## Simple usage example (LED blink)
        ```python
        #!/usr/bin/env python
        """
         Blinks an LED on digital pin 13
         in 1 second intervals
        """
        
        from Arduino import Arduino
        import time
        
        board = Arduino() # plugged in via USB, serial com at rate 115200
        board.pinMode(13, "OUTPUT")
        
        while True:
            board.digitalWrite(13, "LOW")
            time.sleep(1)
            board.digitalWrite(13, "HIGH")
            time.sleep(1)
        ```
        
        ## Requirements:
        - [Python](http://python.org/) 3.7 tested on Windows and macOS.
        - [pyserial](http://pyserial.sourceforge.net/) 2.6 or higher
        - Any [Arduino compatible microcontroller](https://www.sparkfun.com/categories/242) with at least 14KB of flash memory
        
        ## Installation:
        Either run `pip install arduino-python3` from a command line, or run `python setup.py
        build install` from the source directory to install this library.
        
        ## Setup:
        1. Verify that your Arduino board communicates at the baud rate specified in the
        `setup()` function (line 407) in `prototype.ino`. Change it there if necessary.
        2. Load the `prototype.ino` sketch onto your Arduino board, using the Arduino IDE.
        3. Set up some kind of serial I/O communication between the Arduino board and your computer (via physical USB cable,
        Bluetooth, xbee, etc. + associated drivers)
        4. Add `from Arduino import Arduino` into your python script to communicate with your Arduino
        
        For a collection of examples, see `examples.py`. This file contains methods which replicate
        the functionality of many Arduino demo sketches.
        
        ## Testing:
        The `tests` directory contains some basic tests for the library. Extensive code coverage is a bit difficult to expect for every release, since a positive test involves actually
        connecting and issuing commands to a live Arduino, hosting any hardware
        required to test a particular function. But a core of basic communication tests
        should at least be maintained here and used before merging into the `master` branch.
        
        After installation, the interactive tests can be run from the source directory:
        ```bash
        $ python tests/test_main.py
        ```
        
        Automated tests can be run from the source directory with:
        ```bash
        $ python tests/test_arduino.py
        ```
        
        ## Classes
        - `Arduino(baud)` - Set up communication with currently connected and powered
        Arduino.
        
        ```python
        board = Arduino("115200") #Example
        ```
        
        The device name / COM port of the connected Arduino will be auto-detected.
        If there are more than one Arduino boards connected,
        the desired COM port can be also be passed as an optional argument:
        
        ```python
        board = Arduino("115200", port="COM3") #Windows example
        ```
        ```python
        board = Arduino("115200", port="/dev/tty.usbmodemfa141") #OSX example
        ```
        
        A time-out for reading from the Arduino can also be specified as an optional
        argument:
        
        ```python
        board = Arduino("115200", timeout=2) #Serial reading functions will
        #wait for no more than 2 seconds
        ```
        
        ## Methods
        
        **Digital I/O**
        
        - `Arduino.digitalWrite(pin_number, state)` turn digital pin on/off
        - `Arduino.digitalRead(pin_number)` read state of a digital pin
        
        ```python
        #Digital read / write example
        board.digitalWrite(13, "HIGH") #Set digital pin 13 voltage
        state_1 = board.digitalRead(13) #Will return integer 1
        board.digitalWrite(13, "LOW") #Set digital pin 13 voltage
        state_2 = board.digitalRead(13) #Will return integer 0
        ```
        
        - `Arduino.pinMode(pin_number, io_mode)` set pin I/O mode
        - `Arduino.pulseIn(pin_number, state)` measures a pulse
        - `Arduino.pulseIn_set(pin_number, state)` measures a pulse, with preconditioning
        
        ```python
        #Digital mode / pulse example
        board.pinMode(7, "INPUT") #Set digital pin 7 mode to INPUT
        duration = board.pulseIn(7, "HIGH") #Return pulse width measurement on pin 7
        ```
        
        **Analog I/O**
        
        - `Arduino.analogRead(pin_number)` returns the analog value
        - `Arduino.analogWrite(pin_number, value)` sets the analog value
        
        ```python
        #Analog I/O examples
        val=board.analogRead(5) #Read value on analog pin 5 (integer 0 to 1023)
        val = val / 4 # scale to 0 - 255
        board.analogWrite(11) #Set analog value (PWM) based on analog measurement
        ```
        
        **Shift Register**
        
        - `Arduino.shiftIn(dataPin, clockPin, bitOrder)` shift a byte in and returns it
        - `Arduino.shiftOut(dataPin, clockPin, bitOrder, value)` shift the given byte out
        
        `bitOrder` should be either `"MSBFIRST"` or `"LSBFIRST"`
        
        **Servo Library Functionality**
        Support is included for up to 8 servos.
        
        - `Arduino.Servos.attach(pin, min=544, max=2400)` Create servo instance. Only 8 servos can be used at one time.
        - `Arduino.Servos.read(pin)` Returns the angle of the servo attached to the specified pin
        - `Arduino.Servos.write(pin, angle)` Move an attached servo on a pin to a specified angle
        - `Arduino.Servos.writeMicroseconds(pin, uS)` Write a value in microseconds to the servo on a specified pin
        - `Arduino.Servos.detach(pin)` Detaches the servo on the specified pin
        
        ```python
        #Servo example
        board.Servos.attach(9) #declare servo on pin 9
        board.Servos.write(9, 0) #move servo on pin 9 to 0 degrees
        print board.Servos.read(9) # should be 0
        board.Servos.detach(9) #free pin 9
        ```
        
        **Software Serial Functionality**
        
        - `Arduino.SoftwareSerial.begin(ss_rxPin, ss_txPin, ss_device_baud)` initialize software serial device on
        specified pins.
        Only one software serial device can be used at a time. Existing software serial instance will
        be overwritten by calling this method, both in Python and on the Arduino board.
        - `Arduino.SoftwareSerial.write(data)` send data using the Arduino 'write' function to the existing software
        serial connection.
        - `Arduino.SoftwareSerial.read()` returns one byte from the existing software serial connection
        
        ```python
        #Software serial example
        board.SoftwareSerial.begin(0, 7, "19200") # Start software serial for transmit only (tx on pin 7)
        board.SoftwareSerial.write(" test ") #Send some data
        response_char = board.SoftwareSerial.read() #read response character
        ```
        
        **EEPROM**
        
        - `Arduino.EEPROM.read(address)` reads a byte from the EEPROM
        - `Arduino.EEPROM.write(address, value)` writes a byte to the EEPROM
        - `Arduino.EEPROM.size()` returns size of the EEPROM
        
        ```python
        #EEPROM read and write examples
        location = 42
        value = 10 # 0-255(byte)
        
        board.EEPROM.write(location, 10)
        print(board.EEPROM.read(location))
        print('EEPROM size {size}'.format(size=board.EEPROM.size()))
        ```
        
        
        **Misc**
        
        - `Arduino.close()` closes serial connection to the Arduino.
        
        ## To-do list:
        - Expand software serial functionality (`print()` and `println()`)
        - Add simple reset functionality that zeros out all pin values
        - Add I2C / TWI function support (Arduino `Wire.h` commands)
        - Include a wizard which generates 'prototype.ino' with selected serial baud rate and Arduino function support
        (to help reduce memory requirements).
        - Multi-serial support for Arduino mega (`Serial1.read()`, etc)
