A mini project using Arduino on: Bi-Directional digital visitor counter gate and automatic room light controller.

• The aim of our project is to make a controller based model which can sense if any person enters the room, it lights up the room automatically (with different levels) and also counts how many person are actually in the room.
• It is made to prevent electric power waste in schools, colleges, offices and houses. This whole process is operated automatically by sensors.
