摘要：The old, deaf and blind people faces problem in opening and closing of the door in their house as they have to walk to the door to do so. This paper is about the device which is made to solve the problem faced by old people of opening and closing of door again and again, by using an Arduino based remote that can control the door lock using RF module, for receiving and transmitting the data. The product consists of two devices both are based on Arduino. One of the two devices will be fitted at the door that will send the signals to indicate the old person to open the device and will receive the signal to open and close the door lock while the other device will work as a remote consists of chargeable batteries, easy to carry just like a mobile will help to indicate the person carrying it to open the door. The receiving and transferring of signals will be done using RF modules connected to the Arduino boards. The device will help to ease the problem faced by the old, blind and deaf people in controlling the door lock from any part of the house. In future, the RF module in the device to transmit and receive the data can be replaced by Internet of things technology to control the lock from any part of the world. More features like controlling of home appliances, windows etc. will also be the part of this device in future therefore, it has a good future scope also.
