I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because 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 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 ...

It’s been a while since the last top 10 article so I thought it would be nice to make another one for the last 5 months. What I’ve discovered is the fact that people are really enjoying the Arduino ...

For you Arduino fans, here's a great last-minute Halloween project idea from the guys over at Open Electronics: The basic idea is that they are using an Arduino to monitor ambient audio levels and ...

If you solder (and we know you do), you absolutely need ventilation, even for that lead-free stuff. Fortunately, [tinyboatproductions] has gotten into air quality lately and is here to help you with ...

I have an old-ish motherboard with a single 4-pin PWM header and two 3-pin headers. Unfortunately, the 3-pin version of the fan I want is no longer available I'm considering just buying 3 PWM-versions ...
