Automatic Blind Controller Version 2 - Amazon Alexa compatible

thingiverse

Control any blinds, anywhere, automatically with the Automatic Blind Controller - Version 2. This is a completely reworked design, based on a D1-Mini micro-controller. You can now connect your blinds to WiFi and control using a mobile phone app or via Amazon Alexa. An upgraded motor allows for precise calibration of start/stop positions and scheduled opening/closing can be configured from within the app. If you're finding the plastic gear wears over time I have included a revised design that uses a metal coupler. I find the 6mm option works perfect and stops the gear from slipping over time. They are available here: https://www.banggood.com/custlink/KKDGZIzOGb You will also need to use the revised gear surround to accommodate the slightly larger gear.
