To help the development and adaptation of this application to different environments and fans, an MPLAB Mindi simulation of the application was created. The simulation consists of two parts. The first part is a model of a DC motor representing the fan. The second part is all the components needed to replicate the functionality of the AVR DB. Only the op amp components are true representations of the circuits in the AVR DB. The rest of the components are generic circuit elements needed to mimic the behavior of the AVR DB.
