This project uses an ESP8266, stepper motor/driver, some belts, sprockets, and pulleys to turn the IKEA Vidga curtain track system into a motorized, home automation controllable curtain opener.
The system uses MQTT in the current incarnation of the code, so you would need an MQTT server already established, but also shouldn’t be hard to adapt to another solution like fauxmoESP. My code and library is included below, but I have not done a clean up pass, and they were built for my particular setup, so expect to need to make changes. If anyone does the work of genericizing please let me know so I can share for others!

This arduino sketch depends on Encoder, AccelStepper, and my ESPHADevice (below) libraries.
I need to clean up those libraries to make them more shareable, as they are currently special built for my personal use, but wanted to get this out first.
