Tiny Cooling Fan Design Considerations for user experience

In "Tiny Cooling Fan" development areas, many of the industry are used in a dedicated fan control chip, although it is simple, but we have to be designed with smart fan compared, "Tiny Cooling Fan" computing power to handle a far cry from the . On the basis of the functional requirements and cost constraints of careful analysis, we decided to use Motorola microcontrollers MC68HC908AP64 as the core control part of the system, in the evening, when the user approaches "Tiny Cooling Fan", the fan is able to detect the body close to initiate glimmer lighting, user-friendly operation and prevent the user and fan or other objects unnecessary collisions.
