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 ...

I’ve encountered a limitation when using PWM on the RP2040 with the Mbed-based Arduino core: It seems impossible to set a PWM frequency below ~500Hz. This effectively restricts the usable PWM range, ...

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 ...

Using DSO138 Smart Oscilloscope for Testing Arduino Signals The DSO138 smart oscilloscope is a compact and affordable tool for signal visualization. It can be used to test and debug signals generated ...

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 ...

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 ...

I was recently working on an experiment for a new design and was using a function generator. Although new function generators have pretty good frequency tolerance specs, I needed something with more ...

Tsunami is a signal generator built on the Arduino platform. It is the brainchild of London-based developer Nick Johnson at Arachnid Labs and has secured funding on Kickstarter for its commercial ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...
