WS2811 Arduino Basics #4: Control LED-Strip via a Button

preview_player
Показать описание
In Part 1 you will learn how to connect the LED-Strip to you Arduino and you will learn how to control the LED-Strip. In Part 2 I will show you three normal demo programs with nice effects. In part 3 we will write the example programs from part 2 as non-blocking programs. In part 4 a program is written in which you can switch between the three programs from part 3 with the help of a button. In Part 5 you will learn how to control the WS2811 LED-Strip with an IR-remote control. In part 6 you will learn how to display three effects (Rainbow-, Cylon- and Ripple-Effect) simultaneously on a WS2811 LED strip.

Would it be possible to hook these up with like an ultrasonic sensor, so I can have these lights wrapped around my desk with an ideal mode but when when i sit down the lights turn into a different pattern
