The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

We’ve covered plenty of persistence of vision (POV) displays before, but this one from [Vadim] is rather fun: it’s built on top of a PC fan. He’s participating in a robot building competition soon and ...

Your PC will have default fan settings, telling them how fast they should spin at any given temperature value. These are known as fan curves as the higher the temperature of your PC or specific ...

Spend enough time around PC builders and PC building forums, and you’ll learn pretty quickly that the direction of a case or CPU cooler fan matters. When a fan’s positioned for intake, the intent is ...

A new single board mini PC which is a cross between a Raspberry Pi and Arduino board, has been unveiled this week in the form of the new UDOO mini PC. The UDOO mini PC is a single-board ...

LattePanda is an Intel Atom PC running and Arduino (Leonardo clone) combined. Designed for Windows 10, it has a Z8300 quad-core 1.8GHz Cherry Trail CPU, 2-4Gbyte DRAM, 32-64Gbyte eMMC and interfaces ...

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 ...
