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 ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

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 ...

本文介绍一款简单、可重复且高精度的PWM驱动16位DAC设计，涵盖滤波器、OP与误差控制方法... 通过将单个脉冲宽度调制器(PWM)与模拟低通滤波器串接，以实现简单的数模转换器(DAC)，这并不是什么新鲜事了。将最最高有效位2 N PWM输出与最低有效位2 N PWM输出相加 ...

As a result, remote control technologies are being widely adopted across various sectors. Among the many components used in ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

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 ...
