Motorized Roller Shade

I wanted to build a cheap remote controlled roller shade. This uses Blynk and AccelStepper running on a NodeMCU. (Final will run a Wemos D1 Mini)

It is powered by a 28BYJ-48 driven by a ULN2003 board. This is so I could just power it from a standard 5v phone charger. (I would recommend 1a+, but currently have it powered off a USB 2 port on my PC.)

My software project for this:

Note: The gears labeled "(Alternate Ratio)" are near 2:1 ratio instead of near 1:1.
