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 ...
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 ...
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 ...
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 ...
The Arduino library provides a very simple way to generate a PWM signal. The only problem is that the frequency is fixed and all you can alter is the duty cycle: analogWrite(pin, value) where pin is ...
Makers and hobbyists requiring a Nixie tube bar graph to display data in a more physical way, may be interested in a new Nixie Bargraph Kit launched via Kickstarter which offers easy control over two ...
