SunFounder ESP32 Starter Kit
1.8 2.4 Microchip - 74HC595
Welcome to this exciting project! In this project, we will be using the 74HC595 chip to control a flowing display of 8
LEDs.
Imagine triggering this project and witnessing a mesmerizing flow of light, as if a sparkling rainbow is jumping between
the 8 LEDs. Each LED will light up one by one and quickly fade away, while the next LED continues to shine, creating
a gorgeous and dynamic effect.
By cleverly utilizing the 74HC595 chip, we can control the on and off states of multiple LEDs to achieve the flowing
effect. This chip has multiple output pins that can be connected in series to control the sequence of LED illumination.
Moreover, thanks to the chip’s expandability, we can easily add more LEDs to the flowing display, creating even more
spectacular effects.
