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 ...

昨天认识了Arduino，今天来看看Arduino的各种常用开发板。 它有各种型号的，如Arduino Uno、Arduino Leonardo、Arduino101、Arduino Mega 2560、Arduino Nano、Arduino Micro、Arduino Ethernet、ArduinoYún、Arduino Due、Arduino33 ...

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 ...

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 ...

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 ...

最近在设计实例专栏中，人们对一系列以脉冲宽度调制(PWM)控制通用型稳压器(包括线性稳压器和开关稳压器)的简易接口电路产生了浓厚兴趣。这类电路的共通点，是利用稳压器内部的电压参考源，并在稳压器的设定电压分压电阻串联一个分立的FET。jyFednc PWM通过 ...

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 ...

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 ...
