Automatic car parking system project Using Arduino

Hello readers, in the light of the current scenario the problems associated with vehicles parking are increasing day by day. In this article, we are going to make an automatic car parking system project using Arduino UNO. For detecting the movement of vehicles we are using the IR sensors and to display the parking status we are using a 16×2 LCD. You can read the full article with a brief explanation on our website. All the necessary details are provided below.

automatic car parking system project Working?

This system is capable of finding the empty slots that are available for parking automatically. If the slot is empty in the automated car parking the new vehicles are allowed to enter the parking else the entrance is blocked by using the servo barrier in case no empty slot is found by the system. The visitors can see the status for the availability of the free space outside the parking on a 16×2 LCD.

Components Required

• Arduino UNO
• Two IR sensors
• Servo motor
• Jumper wires and a breadboard
• 16×2 LCD and an I2C module
• USB cable for uploading the code
