This document presents a smart parking system using an Arduino microcontroller. It discusses how traditional parking systems are costly and inefficient due to requiring more space and manpower. The proposed automatic parking system addresses these issues by utilizing less space through a multi-level design and reducing the need for manpower. The system overview describes using components like a shift register, IR LEDs, and XBee wireless modules to control the parking and detection of vehicles. Key advantages are saving on space, time, cost and manpower while providing smooth operation without noise or pollution.
