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 ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

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 ...

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 ...

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has him ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Sometimes a design needs more DACs than the mixed-signal microcontroller has available. An easy solution is to put in a ...

This analytical and graphical technique allows engineers to determine, in closed form, the output of an RC filter driven by a PWM pulse train. It is based on the principle that current and voltage ...
