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 ...

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 ...

because some of the pins are not accessible on the Adafruit Feather M0 Adalogger, tested for all pins on the Adafruit Feather M0 Adalogger keep in mind that the resolution is limited to 1000 (unless ...

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 ...

When connecting a LED to a PWM Pin of the Arduino (3,5,6 on Duemilanove) and selecting "output default high/low" in the plugin, the pin can't be set or cleared. When setting it to "PWM 500 Hz" and add ...

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は7月11日、Arduinoマイコンボード「Arduino UNO R4 WiFi」を用いた電子工作入門キット「Arduino Plug and Make Kit」の提供を開始した。7種類のModulinoコンポーネントが付属し、それらを組み合わせてIoTデバイスを簡単に作成できる。電子ブロックを彷彿させるキット ...

A new fully featured Arduino development board has been created called the Prestissimo Uno+ which is now available to back via Kickstarter with earlybird pledges available from just $20, AUS$28 or ...
