Great project video with thorough details sent in by Alex. They write:
Using a NodeMCU, a micro servo, and 3D printing, I created an Alexa enabled
light switch that can be used to turn any “dumb” light switch into a “smart”
device, without needing to modify the wiring in your home. The project runs
off of a pack of AA batteries and is compatible with any device that
integrates Amazon’s Alexa voice assistant. Code and 3D print files are
available in the project’s video description. This is a fun maker project
to get people into DIY home automation, and is good for integrating home
automation into older homes where rewiring light switches, etc. may not be
possible or difficult.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
