1. Project Introduction

This project uses the ESP-12F module to create a smart desk lamp that can use Tmall Genie to voice control the switch and color of the ws2812 light strip. The lamp arm uses a hose with a length of 450mm and an inner diameter of 7mm, and is positioned in all directions.

2. Principles and design ideas

After ESP-12F is connected to the WIFI at home, it is connected to the Alibaba Cloud Life IoT platform to realize Tmall Genie voice control. External ws2812 light strip is connected, and Tmall Genie issues instructions to esp8266 to control the status of the light strip. There are two buttons on the board to reset the distribution network and manually change the color of the light strip.
