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。

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 ...

Arduino-Adafruit-PWM-Servo-Driver-Library.zip,Adafruit脉冲宽度调制伺服驱动器库Adafruit PCA9685脉冲宽度调制伺服驱动器库,Arduino是一家开源软硬件公司和制造商社区。Arduino始于21世纪初，深受电子制造商的欢迎，Arduino通过开源系统提供了很多灵活性。

There was a time when having a blinking blue LED on a project was all you needed to be one of the cool kids. But now you need something more complex. LEDs should not just snap on, they should fade in ...
