So, I am trying to use my RPi model 2B to control a DC motor with an l293d controller. I have moved onto the python3 script and imported the 'l293d' module. Here is my code...

import l293d.driver as l293d
motor1 = l293d.motor(22,18,16)
for i in range(200):
    motor1.clockwise()
l293d.cleanup()

and the error that it returns is...

AttributeError: module 'l293.driver' has no attribute 'motor'

Can someone please explain why this error is occurring. Thanks.

  • Not Pi specific. The message is quite explicit. module 'l293.driver' has no attribute 'motor'. That means there is nothing called motor in the module l293d.driver (whatever that is). – joan Aug 6 '18 at 20:51
  • Did you create a file named l283d.py yourself? That would confuse Python – Dirk Aug 6 '18 at 20:59
  • No, the file is called 'motor.py', but it is in python3. Is this a module for python2 only? – jdw136 Aug 6 '18 at 21:01

If you read the documentation, there are two mistakes in your code. First, just use import l293d. Second, use motor1 = l293d.DC(22, 18, 16)

There isn't a motor attribute, but there is a DC attribute for DC motors.

This runs on my system.

jay@gotham:~/python$ python3 test.py
[l293d]: Can't import RPi.GPIO; test mode has been enabled:
http://l293d.rtfd.io/en/latest/user-guide/configuration/#test-mode
[l293d]: spinning clockwise motor at BOARD pins [22, 18 and 16]
[l293d]: spinning clockwise motor at BOARD pins [22, 18 and 16]

(... Many repetitions of the above line removed ...)

[l293d]: Cleanup not needed when test_mode is enabled.

According to documentation page for the l293d Python library, you've used syntax that's incorrect. The docs suggest this may work:

import l293d  
motor1 = l293d.DC(22, 18, 16)  

then the rest of your code.

  • @NomadMaker called out a mistake in my answer; +1 for him :) I'm going to edit my answer just to eliminate a potential source of confusion. – Seamus Aug 7 '18 at 1:58
