The Alexa communicates with the Raspberry Pi using MQTT messages. Alex has carefully (by asking <a href=\"http:\/\/shop.pimoroni.com\" target=\"_blank\">Pimoroni<\/a>!) found out that the Pi can power the NeoPixel strip without an extra power supply, so it&#8217;s just hooked up to 5V, GND and pin 18 to provide the PWM signal the strip needs via the UnicornHAT library. It&#8217;s a lovely, seasonal project so <a href=\"http:\/\/blog.alexellis.io\/christmas-iot-tree\/\" target=\"_blank\">take a look at Alex&#8217;s blog post here<\/a> and see it in action below:<\/p>\n<p><iframe loading=\"lazy\" title=\"My Alexa Christmas tree with Raspberry Pi + Docker\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/u4aIFOdGP2k?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Alex Ellis has taken a mini Christmas tree, a NeoPixel strip, some jumper wires and an Alexa\/Echo Dot and created an Internet of Things device that is sure to get your blinkiness senses going.
