Micro electromechanical systems (MEMS) (also written as micro-electro-mechanical, Micro Electro Mechanical or microelectronic and Micro Electro Mechanical systems) is the technology of very small mechanical devices driven by electricity and it merges at the nano scale into nano electromechanical systems (NEMS) and nanotechnology. MEMS are separate and distinct from the hypothetical vision of molecular nanotechnology or molecular electronics. MEMS are made up of components between 1 to 100 micrometers in size (i.e. 0.001 to 0.1 mm) and MEMS devices generally range in size from 20 micrometers (20 millionths of a meter) to a millimeter. They usually consist of a central unit that processes data, the microprocessor and several components that interact with the outside such as micro sensors. The main aim of this project is to provide simulation for vehicle. Generally in any vehicle driver drives the vehicle by sitting inside the vehicle. He may not know correct position of vehicle. To provide simulation to driver this project helps you with voice announcement. In this project MEMS connected to ADC and it gives ADC values. We use MCP3202 as ADC and gives values to microcontroller. The microcontroller receives these signals and according to MEMS moments voice announcement coming from APR9600 voice announcement module. Voice announcements like Front, Back, Left and Right. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
