Automatic Curtain With LDR is a devices which is used to ease the users’ life when they need to open or close the curtain in the morning and night respectively. Automatic curtain is a device that used a Light Dependent Resistor (LDR) and it’s sensitivity to detect the light and this LDR will stimulate the circuit to open automatically when it detects light and closed the curtain automatically when there is no light. We also used the logic gate to connect to the rain sensor to detect the rain so the curtain will closed immediately if it is raining outside and this will really ease the user and can save their time with their busy life. Automatic Curtain With LDR also used the power window motor to reversed and foward the curtain’s move respectively.
