I made this project because I wanted a way to automatically control the speed ... output of the PWM pin on the Arduino board. I used an LCD shield to display the current temperature and speed of the ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

To address this issue, he put together a simple but very elegant temperature controlled fan to vent the enclosure when the internal conditions go above the optimal temperature. [Steve] picked up ...

A window is nearby, so I was thinking I could duct it out and set up a fan that would exchange the air if it was cooler outside than inside. I can find regular temperature switches (if temp >80 ...

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 ...

Maintaining water temperature is fairly easy. Controlling a charcoal barbecue is much more difficult. [basement tech] accomplishes this with controlled venting and fans. With the charcoal hot and ...
