#BRUSHLESS DC MOTOR ARDUINO CONTROL PC#

PC cooling fans are almost always brushless.īrushless motors do not like to be driven with a PWM signal. The most common 12v fans in the 10-15CFM range (and sub $15) are clearly PC cooling fans. The airflow from the fan (or lack of) will determine the temperature of the chamber. I will increase/decrease (or turn off) a 12v fan (something like THIS one on Amazon) depending on the current chamber temperature. I will be using a K-type thermocouple to monitor the chamber temperature (with a thermocouple amplifier board between the between the thermocouple and the Arduino). (A 'Mega' is overkill for this project, but this is my first Arduino project and will likely keep the Mega as my 'project development board' and transfer the project(s) to other/smaller Arduinos as they are put into service.) I will be using an Arduino Mega for the 'brains' of the operation. Regulate chamber temperature to maintain the selected temperature using a 12v blower fan (instead of the current ball valves). There are literally two ball-valves that are adjusted periodically (opened more, closed a bit) to maintain the desired temperature. With a charcoal smoker, the chamber temperature is controlled by adjusting the airflow into the chamber. I know that there are several 'smoker' examples around, but most (if not all?) of them are built around an electric (110/220v) heating element as a heat source. I am building a controller for my charcoal smoker. My apologies that this turned out to be such a long post, but I've spent enough time reading on here to learn that the devil is always in the details and it's usually the tiny factiod that finally comes out 20 posts down that determines the solution. I am in the process of selecting the components for my first Arduino project and would appreciate your advice so that I can continue procuring components/modules.
