PCBWay 3rd PCB Design Contest

Automatic Light Switch


Hello, my name is Restu, I am a computer science student in Indonesia. I really like making automation projects that can solve problems such as home appliances or vehicles.


My project this time is an automatic light switch where this automatic switch will work for lights on the porch of the house or on the yard. By using the Real Time Clock chip as a timer that will turn on and turn off the lights automatically according to the sun sink and the sun rises. This project has been created using Arduino nano with an ATmega328 microcontroller which is coupled with a relay module and an RTC module using a jumper cable.


For the development of the next project, I want to make a PCB to briefly connect all components and reduce the size of the automatic light switch.

Hopefully PCBway can realize my desire to develop this project so that this automatic light switch has a compact size so that it is practical to implement on the home porch light switch. This project will be very useful for some people who often leave home late at night so that the house left behind is not pitch black when night falls.
