Blind Stepper Motor

Material List:

• 1x 28BYJ-48 (5V)
• 1x Stepper driver board uln2003
• 1x NodeMCU
• 1x 608rs bearing
• 1x M8 x 16mm bold
• 1x Powersupply 5v 
• 2x Screws and dovel to mount it to the wall
• 9 - 13x M3 x 10mm Screw
• 2x M3 Nut

I did use a universal PSU with 30W and was put the Voltage to 6V You can even go up to 9V but when you connect the NodeMCU make sure to use the VIN Connector.

I use ESPHome with this configuration

The 52000 in the code is the steppes needed to go all the way down. This you have to figure out yourself for your window.

For windows that are right next to each other there is a 2x version so you only need to use one NodeMCU.
