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 ...

In the previous chapter, we stored the current state in a variable and switched the LED operation mode every time the button was pressed.The signals sent to the LED so far have been of two types: HIGH ...

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 ...

What sorts of things do you use PWM for? There are lots of very clever uses for PWM. However, there are two applications which account for most PWM applications - voltage or power modulation and ...

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 ...

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 ...

If your Arduino runs out of I/O lines, you can always add one of the several I/O expander chips that takes a serial interface to set its several pins. Or perhaps you could buy something like an ...

One way around the problem of getting a fast response from a microcontroller is to move the problem away from the processor. In the case of the ESP32 there are some built-in devices that can use GPIO ...
