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 ...

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 ...

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 ...

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 ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using the ...
