As connected as we are, reliable and affordable internet is still a luxury in the far reaches. [kohleick’s] country home is not just remote; with temperatures dropping to -30C in the winter, it’s ...

Recent Arduino projects are blending AI-assisted coding, advanced thermal and environmental sensors, and cloud connectivity. Tutorials now show how to build systems with MLX90640 infrared cameras, ...

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 ...

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [Rick’s] ...

To make a remote temperature sensor with the LTC2970, run two different currents (ILOW and IHIGH) through the transistor and measure VBE at both currents (VBE_LOW and VBE_HIGH). The difference between ...
