DIY SmartBlinds v1 - Vertical or Horizontal Blinds Automation Project

thingiverse

This is a DIY project that requires electronics, soldering, the Arduino IDE, and basic knowledge of uploading code to a compatible board. You can follow all the relevant step-by-step instructions on my blog page here: http://www.candco.com.au/2019/03/10/diy-vertical-or-horizontal-blinds-automation-project/ To complete this project, you will need to source the following components: * A 5V Stepper Motor (28BYJ-48) with a Drive Test Module Board ULN2003 * A WiFi NodeMCU CP2102 Development Board that operates on 2.4GHz frequency * M2.5 x 8mm long Counter sunk screws in quantities of eight * M2.5 x 8mm button cap screws, either four or eight, for internal PCB mounts * One or two M4 x 5mm long Steel Hex Grub screws for securing the cog mount to the motor shaft * A 5.5mm x 2.1mm DC power plug * A 5v Power Supply with a 2.1mm DC plug The total cost of this project should not exceed $20-$25 AUD. I have designed the base so that it can be printed upright and without supports, but this may require some level of 3D printing experience. The only component that I would recommend printing with supports is the chain cog due to its dimples on the inside. For optimal results, print the base on its largest flat surface.
