In our case fanSpeed will have a value of 32 at tempMin and 255 at tempMax. These values are used to control the speed of the fan using PWM and the analogWrite(). The fanLCD re-maps the temp to allow ...

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 ...

This is the type of thing you could throw together with a microcontroller hobby board (i.e. Arduino and the related diaspora), a couple temp sensors (whether thermistors on analog pins or I2C temp ...

The GND of the 9V battery is not connected to the GND of the arduino. So, this cause the fan unable to move even if the temperature exceed the threshold temperature. Solution 1. Connect the GND of the ...

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, … ...
