Temperature-dependent fan control using Arduino
I’m building a box to dampen the noise of the projector I bought (more on that in a later post) and to keep it cool I added two fans, one sucking cold air in and one pushing warm air out. To reduce the noise as much as possible I wanted to run the fans as slow as possible, but of course they should still run fast enough to properly cool the projector. So I built a little fan controller with an Arduino that uses temperature to determine the fan speed. Read more
