The device is simple to use: just simply connect the PWM capable fans to the board, and power it using a 12 V DC power supply. The device uses an LCD screen to show information. The LCD screen turns ...

Traditional fans run continuously or require manual control, often leading to energy waste. This project creates a smart solution: a temperature-sensing fan controller that turns ON/OFF or adjusts ...

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 ...

It’s probably not much of a stretch to say that many of us have taken on a project or two that were little more than thinly veiled excuses to add a new tool or piece of gear to our arsenal. There’s ...
