Aruna , need some help.

[dkelly324]

I'm trying open and close my vertical blinds with your wemo emulator. Everything works fine until I increase the run time on either a servo or stepper. Alexa will tell me something went wrong and do another run. I've added a 6 second delay after test lights on and off in the single switch example and the same thing happens. Help

can you share your code? You must be blocking the loop()

[dkelly324]

Ok, I’ll get it to you tomorrow.

Aruna, just remember I'm no C++ guy so I've pieced this together the best I could. The sketch labeled blinds contains your original emulator but they both do the same thing. Once the run time on the stepper or the servo is increased to about 3 revolutions, it starts having problems.

Thank you so very much for your help. Dennis Kelly dkelly324@gmail.com

[kakopappa]

your problem is you are using delay(). Delay will block the main loop and stops everything (except interrupts) try using a timer to control the stepper.
