SunFounder ESP32 Starter Kit
1.7 2.3 Colorful Light
In this project, we will delve into the fascinating world of additive color mixing using an RGB LED.
RGB LED combines three primary colors, namely Red, Green, and Blue, into a single package. These three LEDs
share a common cathode pin, while each anode pin controls the intensity of the corresponding color.
By varying the electrical signal intensity applied to each anode, we can create a wide range of colors. For example,
mixing high-intensity red and green light will result in yellow light, while combining blue and green light will produce
cyan.
Through this project, we will explore the principles of additive color mixing and unleash our creativity by manipulating
the RGB LED to display captivating and vibrant colors.
