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 ...

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 ...

A programmable temperature and process controller for use by the maker community has been designed to be Arduino-compatible. Called the SmartPID it can be programmed on a PC via the USB port using the ...

You will need a pull-up resistor of about 5 KOhm between the 1-Wire data line and your 5V power. If you are using the DS18B20, ground pins 1 and 3. The centre pin is the data line '1-wire'. This ...

With the compliments of the Elektor Editorial and Labs teams, here is a 'fresh' article presented free of charge to all Elektor e-zine subscribers. This time we have author Werner Möhrle discuss his ...

[Jason] learned a lot by successfully automating this meat smoker. This is just the first step in [Jason’s] smoker project. He decided to begin by hacking a cheaper charcoal-fed unit first, before ...

We’ve probably all seen USB soldering irons advertised for very little money, and concluded that they might not necessarily be the most useful of tools. The cheapest of these lack any real temperature ...

I've got a storeroom in a garage that has some stuff in it that is a little more temperature sensitive, and has more variability than I'd like (it also has some equipment that generates a bit of heat, ...
