This project is a combination of several other projects. It consists mainly of:
Huge thanks to the two above!
I use this in my Home Assistant setup, but you can use it with any kind of MQTT broker. When using with HASS, you can make some really cool automations, like making the roller blinds go up in the morning when your alarm clock rings!
I originally started this project by following the Instructable linked above, but never got quite comfortable using lua and I think the motor shield I had was broken when it arrived. Still the parts designed in that Instructable was perfect as I already had the IKEA Tupplur roller blinds.
I still had to design a new case for the controller, since I ended up with making my own development circuit.
Parts used:
- NodeMCU V3
- 12V to 5V converter - Did not realize untill after the project was finished that the NodeMCU did not need the converter as it could handle the 12V
- ULN2003 stepper motor driver
- 12V power supply
- Power plug
As I mentioned I did not end up with using the code in the Instructable. I therefore searched around the web and found the code linked above. It worked perfect!
