The Python Arduino Prototyping API helps you to quickly prototype Arduino programs, without having to repeatedly load the program to the Arduino board.

1. Load prototype.pde onto your Arduino dev board.
2. Import the arduino lib in your python script.

Arduino.output(list_of_output_pins) - set the output pins

Digital I/O

1. Arduino.setHigh(pin_number)
2. Arduino.setLow(pin_number)
3. Arduino.getState(pin_number)
4. Arduino.getState() - returns true if pin state is high, else it returns false.

Analog I/O

1. Arduino.analogRead(pin_number) - returns the analog value
2. Arduino.analogRead(pin_number, value) - sets the analog value

Misc

1.) Arduino.turnOff() - sets all the pins to low state

2.) Arduino.close() - closes serial connection. Using this makes sure that you won't have to disconnect & reconnect the Arduino again to recover the serial port.

    #the blink program

    #import the lib
    from arduino import Arduino

    import time

    #specify the port as an argument
    my_board = Arduino('/dev/ttyUSB1')

    #declare output pins as a list/tuple
    my_board.output([11,12,13])

    #perform operations
    i=0
    while(i<10):
        my_board.setHigh(13)
        time.sleep(1)
        my_board.setLow(13)
        time.sleep(1)
        i+=1
