用NodeMCU显示时间，用Arduino监测温度；可以选择在每秒钟改变显示的颜色。 迷你LED的额定电压是3.0V到5.5V，16mA（每个LED）。 我们的NodeMCU有3.3V的稳压器，可以正常驱动所有的LED。 第2步：LED WS2812B 3030 这里使用了WS2812 NeoPixel Led，它带有集成的IC，这样我们就可以对 ...

Description: Using a bunch of WS2812B led chipset I build a net of lighting for my jumper, this is the first version so do not expect too much from it, version 2 is on it's way. I designed the small ...

Neopixels and other forms of addressable LEDs have taken the maker world by storm. They make it trivial to add a ton of controllable, glowing LEDs to any project. [Arnov Sharma] has made a great ...

Today, we’re going to explore the uses of addressable LEDs. Addressable LED is an easy way to add complex lighting effects to any project. Each addressable LED has an integrated driver that allows you ...
