Circuit Automatic Room Lock and Light Circuit

Abstract

Nowadays electronics had become something important to our daily life. The development of the new technology had been made to improve and give something good to the daily life using the advancement that has in today world. With technology also we can show that the current supply can be save and can be controlled by today technology. That can be see the technology that is call microcontroller 8051. That one of the latest technology that can be coding and can be program. Using that technology, the circuit that can control that can become the switch for the lamp. From the study that had been made the circuit can be made from the combination of the sense, microcontroller and some other component to make the circuit that been called “Automatic room-lock and light circuit”. With this circuit, it can give more benefit to their user to make sure that current saving will become one of the real things on this day. This circuit will make person did not to worry anymore about the light did not be off when did not has anybody in the house, room and the other closed place that need the light as a source to see that place.
