You must accelerate the mass by applying torque sufficient to overcome the inertia and get the motor moving and then there must be enough time to get it to the next position. If you step too quickly, you will move only slightly, falling back, to the original position, which would give you the described symptom. In your code, if you enter a value larger than 1000, you will have a step time of one second, and the motor will move (albeit slowly) if this is your problem. | |

| Jul 14, 2017 at 18:55 | comment | added | NeonCop | @Andyaka That's a smart idea, but I actually think that the L293D is designed to handle specificlaly the voltage of my motor (12V), so I don't think it's a problem with the voltage being too low. Also, my battery is actually 12V I'm using a DC power supply. | |

| Jul 14, 2017 at 18:14 | comment | added | Andy aka | It might be this: electronics.stackexchange.com/questions/108686/… and please note that running from a puny 9 volt battery (as shown in your cartoon) will not work either. | |

For a RPi, you only need to indicate the connections to/from it. Or you can use a pencil and paper and add a photo to your question, but that is not the preferred method. | |
| Jul 14, 2017 at 17:56 | comment | added | NeonCop | @AndrewMorton Is there any software that you would recommend? Also how would I put a Raspberry Pi or motion sensor into the circuit diagram it's not as easy as a motor or a battery. | |
| Jul 14, 2017 at 17:37 | comment | added | Andrew Morton | @NeonCop Adding a circuit diagram to your question would be best - you have shown us a wiring diagram, which is not the same thing. | |
| Jul 14, 2017 at 17:29 | comment | added | NeonCop | how would you prefer I format it? It's no big deal I can redo it in 5 minutes... I'm new to this EE thing so I'm not sure about standards and stuff like that | |
