Python Arduino Prototyping API (version: 0.5)

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

Setup:

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

Methods

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.analogWrite(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.

Usage example

    #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
