AMSpi

Python class for controlling Arduino Motor Shield L293D from Raspberry Pi (using RPi.GPIO)

Requirements

• RPi.GPI, on Raspbian you can install it typing this command:

sudo aptitude install python3-rpi.gpio

Connecting Arduino Motor Shield L293D to Raspberry Pi

You can wire it up as I did. Just look at the colors :-]
(Update 09/2016: Fixed image of wiring - thanks to Maxime!)

Example

For complex example please have a look to example.py source code.

from AMSpi import AMSpi

# For BOARD pin numbering use AMSpi(True) otherwise BCM is used
with AMSpi() as amspi:
    # Set PINs for controlling shift register (GPIO numbering)
    amspi.set_74HC595_pins(21, 20, 16)
    # Set PINs for controlling all 4 motors (GPIO numbering)
    amspi.set_L293D_pins(5, 6, 13, 19)
    # Run motors
    amspi.run_dc_motors([amspi.DC_Motor_1, amspi.DC_Motor_2, amspi.DC_Motor_3, amspi.DC_Motor_4])
