所以,我们现在可以从 Raspberry Pi 的命令行来改变灯条的颜色。但是,我们想做的是从 Amazon Echo 来改变颜色。 首先让我们设置一个Web服务器,让 Amazon Echo与Pi进行通信。 按照此官方指南在您的Raspberry Pi上设置nginx:https://www.raspberrypi.org/documentation/remote-access/web-server/nginx.md 确保也安装好...

The top LED is wired up differently. A line runs frompin 12(GPIO18) of the Raspberry Pi into the positive side of the LED, which runs through the resistor and back into theGNDrail. Pin 12 is also GPIO18, as confusing as that sounds,our guide to Raspberry Pi GPIO pinswill help clear...
Recently I collected several Chinese LED party/disco lights to try out some funny hack ideas.The first trick is to drive the LED assembly inside the lamp through my Raspberry Pi Pico setup while holding the orbing mechanism and power supply section of the lamp intact. I’ll keep working on...
Flowing Lights树莓派流水灯制作v.qq.com/x/page/p0545gfqpfr.html Introduction 此章我们将会学习如何让八个LED产生你想要的多种闪烁效果,当然,还是在树莓派的基础上进行试验。 What you will need 树莓派×1 线路板×1 网络电缆×1 LED×8 电阻(220Ω)×8 跳线 Experimental Principle(实验原理) 通过编...
[60] investigated the communication mechanism of a DALI network of a group of lights with a Raspberry Pi over MQTT (Message Queuing Telemetry Transport) protocol, used for energy usage optimization purposes. Compared to existing work, this paper focuses on the development of an embedded DALI ...
杜邦线4条。3根连接红色绿色蓝色,还有一根连接树莓派5V电源引脚。 原理说明 这个RGB彩色LED里其实有3个灯,分别是红灯绿灯和蓝灯。控制这三个灯分别发出不同强度的光,混合起来就能发出各种颜色的光了。 LED灯上的4根引脚分别是VCC,R,G,B。 VCC需要接到电源正极。我们把它连到树莓派的5V引脚上。 R,G,B分别...
LED lights. Registers Connections: First connect the Motion sensor to the Raspberry Pi using the GPIO pins. There are three pins on Motion sensor which are VCC, GND, OUT. VCC is connected to 5v supply on raspberry pi, out in connect to the pin in which you want the input, I connected...
it might as well be the most controllable light source available: a strand ofdigitally addressable RGB LEDs. Another goal of the project was to make sure I could control the lights remotely-- there's no buttons on the Raspberry Pi I can use, plus an external interface is much more customi...
