Hand Movement based Fan Controlling
The main aim of the project is to control the direction of the DC Motor. A motor is anelectromechanical device, which converts electrical pulse into discrete mechanical movement.The shaft or spindle of motor is incremented in discrete steps when electrical command pulse isapplied to it in the proper sequence.The motor rotation has several direct relationships with applied input pulses. The sequence of theapplied pulses is directly related to the direction of motor shaft rotation. In this project wecontrol the fan by using MEMS technology. In MEMS we have tilt register. When we change thedirection, the tilt registers values are changed and that values are given to microcontroller.Microcontroller compare this values and depending up on tilt register value occurred in mems icthe controlling of fan is done by using microcontroller.Here we will show fan on/off and two different direction according to the mems input. Themicrocontroller will take input from mems and according to mems data the fan is beingcontrolled. This project uses regulated 5V, 500Ma power supply, 7805 three terminal voltageregulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the acoutput of secondary of 230/12V step down transformer.
