More torque #21

Closed lexucd closed 3 years ago

lexucd commented 3 years ago

Do you think that the L293D motor driver could be added instead of the 2003 for more torque? I saw something interesting here :https://lastminuteengineers.com/stepper-motor-l293d-arduino-tutorial/ Or even turning the 28BYJ-48 bipolar might do the trick for heavier rolls. But i guess the libraries would need to change...? (advanced noob in arduino and electronics)

P.s. Amazing work you are doing here!!! Thank you a thousand times for myself and others that did not take the time but used your work.

Hi, take a look at this issue: https://github.com/kp-bit/xblinds/issues/20 - you won't necessarily need other libaries if the other driver is connected to 4 pins... Thanks for your input, enjoy!

Tried it but it only turns clockwise when I try to set it up with + and -. And also, after I enter the MQTT details, the device cannot be accessed from the local ip anymore, i have to re-flash it to enter the local ip again. (not that i've mannaged to make it work with cloud MQTT anyway - node02.myqtthub.com )

Are you using the ULN2003 or the L293D driver? If it's the ULN then you might have a defective driver/stepper or faulty wiring. As for the MQTT server, you need to use an IP address, there's no DNS client in the code...

I am trying the L293D now. They work great with the ULN2003 but I would like a bit more torque as it skips some "beats" when opening

You might be wiring it wrong... Try setting up a piece of code with the AccelStepper library with the correct pinout and see if it works as intended.
