Today, technology has transformed humans' lives in all areas. Technology can be found in everyday life in the form of smart factories, smart cities and smart rooms. Thus, smart systems and devices are having a great effect upon human activities. Together with improving technology, in the last 50 years, the human population has seen an expeditious and substantial increase. The number of cars has also substantially increased and, as a result, parking spaces and car park have become more important. Areas in which to park cars have become wider in scope, including inside huge buildings; thus, the management of them become more difficult and complicated. Being able to discover an empty parking space as soon as it is needed is vital for both driver and multilevel parking garage owner, especially for the former, in order to avoid losing him/her time and money in a crowded city. Thus, we designed a smart car parking system, which is managed by Arduino control. Our main aim includes reducing time loss and the amount of fuel consumed while trying to find a parking space. By reducing the amount of consumed fuel, it will be possible to reduce air pollution levels, together with minimizing the negative impact on domestic finances caused by car usage.
