This paper presents a new approach to utilize smart technology in a practical and meaningful manner to make finding seats easier for audiences in cinema halls. Generally, the audiences come to cinema halls late and they cannot find their exact seats easily, because there are many places to sit and many small signs (numbers, letters etc.) to define them. Especially, the low lighting of these halls makes seeing seat's number and/or letter much harder. Due to these reasons, smart cinema seat system has been designed by using lights inside the seats which can catch the attention of people. The system is based on an Arduino microcontroller board with a group of sensors and an Android application that can communicate with the microcontroller and server database of the cinema. The lights and sensors have been connected to Arduino microcontroller board and the board has been controlled with the Android application (App) via Bluetooth protocol. The proposed system is a novel idea for smart technology and the results showed it has worked successfully and helped people effectively in finding their seats.
