Final Project

Easy control, Easy to get, and Easy to express your emotion!

This is an Easy light controller. You can make the color by yourself and memorize 4 colors in this box. You also can directly adjust the color at the light.

Hero Shot

Light Controller

We control and memorize the lights on a display.

Code

The code of this project is Arduino IDE.

Code name Function
alacolour.ino Controller side: Manage color and send it to the light system
wifi_client_xiao.ino Light side: Receive the data and light LED

anacolor.ino

This code has 2 functions, wifi network and colour control. It starts web server and send colour data into the light(Xiao C3). It also shows 3 menus for colour control, Main menu, Setting menu, Execute menu and Live menu.

wifi_client_0531.ino

This code is light part and wait for the signal from wifi client
