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 ...

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 ...

The good thing about computers is they do your work for you, right? If you are a programmer, that doesn’t always seem to be a true statement. [Runtimemicro] has the answer, at least if you are writing ...

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 ...

PWM的应用可以说非常广泛，控制电机速度、灯光亮度、通信调制等众多领域。 PWM的问题小伙伴问的比较多，最近也在用PWM，这里就分享一下关于PWM的一些内容。 什么是PWM？ PWM：Pulse Width Modulation，脉冲宽度调制。 网上的解释很多，通过下图，你就能直观的理解 ...

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 ...

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 ...

Ynformatic has this week published details on how to use your iPhone together with a little Arduino hardware and programming to create some awesome polarised images similar to the one above. The ...

According to Tom's Hardware, the railroad equipment came from T-gauge, a hobby company specializing in small-scale components. For now, the conductor is using an Arduino on ...
