Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

技术创新始终是产品变革的核心推动力之一。在LED全彩显示屏中，有一种技术为大众所熟知——“外部脉波宽度调变(外部 PWM)”。而随着市场对显示画面效果提升的需求增加，技术革新进一步发展，Scrambled PWM(简称 S-PWM)技术应运而生，为LED画面带来全新显示效果。

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has him ...

升级后的简易LED显示屏，保留了相同的界面，但增加了更多功能··· 图1这种设计思路展示了如何轻松地“让老树开新芽”，以及如何在之前发布的简易LED显示屏上添加一些新功能。Yfeednc 图1 升级后的简易LED显示屏，保留了相同的界面，但增加了更多功能。

LED 是通过 1 – 10 V 模拟电压、电源相位角、电源线、DALI 等数字输入或 WLAN 链路调暗的，实际上只有两种方法可以真正调暗 LED ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

汽车大灯制造商可以使用SEPIC拓扑来实现直接由车辆电池供电的远光或近光LED阵列驱动器，而非使用升压后接降压转换器的传统两级拓扑或全桥降压-升压拓扑。AL8853AQ的SEPIC功能支持经济高效、简单的降压-升压型拓扑，非常适合平视显示系统，即汽车设计中日益流行的功能。

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...
