Voice Command Based Opening and Closing of Refrigerator Door
Journal Title: GRD Journal for Engineering - Year 2018, Vol 3, Issue 7
Abstract
With new technologies surfacing day-by-day, we can use them to make new products and even can modify the existing ones. In a practical implementation, it is possible to use electric motors to open and close a refrigerator door. This can be done by reversing the direction of motion of motor when required. Reversing the polarity of the starter winding will solve the purpose. There are many ways to operate a motor and control of motor from human voice is one of them. In this application, a microcontroller-based voice input electronic circuit is designed, which can be used to rotate the motor in the required direction and hence to open and close the refrigerator door. The motor is connected to the axis of the refrigerator door. The relays are connected to the electric circuits for straight and reversed polarity. The motor operates in a direction as commanded. Microswitch are used to send signal to the microcontroller, which further stops the power supply to the relay and ultimately stops the motor rotation.
