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 ...

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 ...

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。

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 ...

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 ...

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。

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 ...

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 ...

Freescale Semiconductor has introduced the MC34845 LED driver with high-speed pulse width modulation (PWM) capability. This six-channel device is designed to allow LED backlights to operate at ...
