QUESTION

Programming in Python: Controlling Stepper Motor + Raspberry Pi Zero + L293D IC

Asked 2018-Nov-23 at 09:52

(Warning! I am not educated on this topic)

Hey folks. I'm posting here because I have a friend who desperately needs help with her project. I'm familiar with scripting, but not too much with programming. I do work in IT, so I'll do my best to provide the necessary information. She's trying to program a Raspberry Pi Zero to control a stepper motor using Python 3. Simple as that.

She followed these tutorials. Looks like she used the parts and wiring from #1 and the code from #2:

Helpful pictures here. This is her actual setup: https://photos.app.goo.gl/WJbCo4UU3wAdo8913

Helpful notes: She mentioned she is not using a resistor between the power source and the L293D Driver IC.

Parts Used:

-Raspberry Pi Zero (Pi 2 or 3 was recommended, but the Zero has the same pin-out as the 2 & 3. She just had to solder on her own double-header)

-12V DC Power Bank

-Nema 17 Stepper Motor (https://www.amazon.com/STEPPERONLINE-17HS13-0404S1-Stepper-Motor-Printer/dp/B00PNEQ9T4)

-L293D Motor Driver IC (https://www.amazon.com/NDRTJM-SHOMPFL1045-L293D-Stepper-Driver/dp/B008XCGLNM)

-Breadboard w/ jumper cables (Duh!)

The code that she's using is below. When she attempts to run it, the motor just vibrates. Seems like it's repeatedly taking a step forward and a step back. No error codes are received. She also tried using another Nema 17 Stepper Motor that drawed 2A, but dropped down to the Nema 17 that draws .4A and gets the same result.

It looks like you're most of the way there... but the particular sequence isn't making the stepper step. With the L293D, the IO pin values are essentially what we drive the coil with, and I guess here coil_A and coil_B are the two coils with 1 and 2 being the ends of them (two coils is typical in a bipolar stepper motor). So the states you've applied are:

QUESTION

The right motor on my line sensor Arduino robot runs even when the requirements to run it are not met

Asked 2017-Aug-27 at 03:53

So in this Arduino code for a line sensor robot using RedBot line sensors, the right motor seems to be running even when both sensors are detecting black (a line). This does not happen on the right motor so I suspect it has something to do with the first "if" statement.

The motor does stop however when only the right sensor detects black and this makes only the left motor run. I'm not sure what the problem is that is making the right motor run even when its condition isn't met and this is not a problem with the sensor btw. I am using an L293D motor driver to control the motors but I doubt it has anything to do with that.

QUESTION

Using Arduino and Motor Shield

Asked 2017-Apr-15 at 23:41

I am a beginner in Arduino.

I want to connect 2 motors to Arduino. Why do we require txhe motor shield? And if yes please explain why is it required? Also can I use an amplifier for the same.

Another question, I have SLAEX039 L293D Motor Shield. Does using this motor shield restrict arduino's pin usage? I mean we can't use the arduino pins if we use the motor shield right, can we?

Thank a lot

The core reason that we require motor shields is because the Arduino, on its own, cannot power a motor with its IO pins.

The digital IO pins on the AVR based Arduinos (such as the Uno) are only rated to supply up to 40mA of current at 5V - they are designed for signalling hardware, not driving loads such as motors, that can run to several Amps at higher voltages at peak loads.

Fortunately, there are devices that are designed to control heavy loads such as motors based on these logic level signals - we typically call these drivers. The L293D is such a driver, which connects to a logic device like the Arduino for signalling and then drives a motor from another supply.

While you can use a cheap, standalone L293D device on its own, it's often more convenient to use one carried on a shield, which correctly connects the driver as well as provides connectors for the external power and motor.

Ultimately, you don't require a shield, but you do need some form of driver to take the logic level signals from the Arduino, and shields are convenient ways of providing these.

http://www.ti.com/lit/ds/symlink/l293.pdf is a datasheet for a L293D device from TI, showing the various ways it can drive a motor based on the signals it receives.

Vulnerabilities

No vulnerabilities reported

Install l293d

You can install using 'pip install l293d' or download it from GitHub, PyPI.
You can use l293d like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
