This project speaks for itself – it serves as simple dual lamp switch with delay timers. Project is really easy to build as it uses few components.
Each lamp is controlled by button. When one of the buttons is pressed – lamp is turned on via relay. After predefined time lamp turns off. This might be convenient where lamp is needed for short time, for instance while you go upstairs, or just when you entering the house and need light to find a regular lamp switch. Project files including source code and PCB files are available for download.
