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 ...

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 ...

Intro:For 3D pinting, different filament (ABS, PLA etc) requires a suprising accurate temperature for extrusion to get the best results. Then, even using a specific type, different colours may work ...

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 ...

[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 ...
