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。

LED照明凭借着节能、高效、长使用寿命等优势成为当下异常火热的一个领域；具有节省能源、提高生活质量、改善光源效能 ...

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 ...

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。

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

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 ...
