The goal of this project is to create a lower cost alternative to motorized curtain rods, as well as making curtains WiFi controllable.
The current set up uses a NodeMCU and LLC as a pseudo WiFi shield. Because of this, there are two Arduino sketches. The sketch for the “shield” hosts a REST server, with an endpoint at “/curtains” that accepts the parameter “command.” The sketch for the base Arduino Uno receives serial commands from the shield, and runs the motor accordingly.
Additionally, I would like to add hall effect sensors at the center and one end of the curtain rod to detect when to stop running the motor, rather than relying upon a finite passage of time.
A future version might remove the Arduino Uno and motor shield in favor of using only the NodeMCU and a motor driver.
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
