Introduction Dental care has been an important part of personal well-being for many years. Evolving from the ancient toothpicks, traced back over five thousand years in ancient civilisations, the traditional toothbrush as we know it today was developed in the seventeenth century . Since then the toothbrush has maintained the idea of being a “brush” while other aspects such as handle shape and toothbrush material have changed over time to become the toothbrush as we know it today. Efficiency has become necessary in the modern age due to the massive human population and societal pressures on time. Studies describe the possibility of improving the efficiency of the toothbrush by using a electric toothbrush. It has been found that the removal of oral gingivitis and plaque is related to the frequency of brushing and the technique used. With an electric smart toothbrush, the frequency of brushing can be adjusted to be much more optimal than human brushing frequencies on the teeth. The smart toothbrush can also be integrated with sensors to aid the user in practising more efficient tooth brushing techniques. Recently, with the development of faster smaller and faster microcontrollers, it is possible for the toothbrush to process even more data while being lightweight and compact. Human machine interface and communication has therefore become an important factor for product marketing and development. In this project, the design will explore all these aspects and seek to produce a simple prototype using basic resources to achieve a smart system aiding the user to operate the electric toothbrush. Finalized Specifications  Clock-wise and anti-clockwise rotation  Adjustable speed  Long head for better cleaning  Ultra violet light to kill germs  Programmable brushing modes for different requirements  Timer to automatic stop brush to save energy  Long lasting battery upto 2 months(assumed brushing 2 times a day and 2 mints for a session )  Led display showing current states of battery , mode, speed and countdown timer  Curves in design for better grip  Mouth washer tank Systems Design and Integration Toothbrush will be controlled using an surface mounted AVR Atmega8 microcontroller, It will use simple dc motor controlled using PWM technique. LED display is integrated so to display current states Motor Driver IC As the microcontroller is unable to provide the required current to drive the motor, an external IC driver is used and controlled by the Atmega8. The L293 driver chip is designed to drive currents of up to 1 A at voltages from 4.5 V to 36 V ]]>
