The wires for the power supply need to be passed through the large hole which also accommodates the back end of the stepper motor. Tidy the wires into the housing whilst ensuring that the USB connection on the Feather Huzzah is not obstructed. ![]() Handle this carefully so that none of your wires work themselves loose.Īfter the second breadboard has been fitted you can remove the temporary bolt as the breadboard will keep the nut in place. ![]() Peel the adhesive of the second breadboard and fit this against the opposite side of the housing. If you struggle to hold it in place you can temporarily partially insert one of the bolts. If the self adhesive is not holding your breadboard in place you can add some hot melt glue to help things stay put.īefore we add the second breadboard we need to fit one nut behind the hole I'm pointing to in the above images. Ensure that it is slid all the way to the right and as far down in the housing as it will go before applying pressure to fix it in place. Peel the self adhesive cover off the back of the breadboard which has the ESP8266 on it and position inside the housing so that the sticky adhesive is facing the stepper motor. įinally the 3D printed parts can be downloaded from here: įor this part of the build you will need to print the file 'lid.stl' whilst it prints we can continue as below. The code can be downloaded from Github here. ■ Battery powered glue gun: (not something you have to have but I recently got one and it's made gluing things together super easy). ■ Nema 17 Stepper Motor: ■ A4988 Stepper Motor Driver: ■ Adafruit Feather Huzzah ESP8266: ■ Mini Breadboards x2 (self adhesive): ■ Breadboard Jumper Cables: ■ Braided fishing wire: ■ Long USB A to USB Micro B Cable: ■ 100 Capacitor: ■ Switched Battery Holder for 8 AA Batteries: ■ Nuts and Bolts: M4 Nuts x2 M4 x 10mm bolts x2 M3 x 10mm bolts x 4 ■ 8x AA batteries ■ About 100 grams of plastic for the printed parts. Here is a list of the items used in this project and where you can find them: You can also use with other SwitchBot devices for better automation and scene control.You'll need a few items before we start to assemble your curtain automation system. Control your curtains via the Home App or using your HomePod/Apple Watch.
