WIFI RGB Lamp
Lucie has a broken leg and is in the sofa. It is getting darker outside and she wants to light a lamp. Standing up and walking are difficult. Can you help make a lamp that she can switch on and off with her smartphone?
In this workshop, an RGB lamp is built that you can control with your smartphone. Change the intensity of the three basic colors to create mixed colors.
This example of additive color mixing is also used in an LCD (Liquid Cristal Display) screen.
