This blog will show you how to design and create a Car Parking System using a Seven Segment display interfaced with Arduino Uno. You just need some components, and I assure you this project is gonna be fun!
Components Needed
- Bread Board
- Jumper Wires
- Resistors (1 ohm)
- Arduino UNO
- IR-Sensors (2x)
- 7-Segment Display (Common-Cathode)
Adding Arduino Library
Proteus doesn't come up with Arduino Libraries. We are using Arduino Uno in this project, so manually installing Arduino libraries in Proteus Professional.
You can use the path if it works for you. In my case, it works.
C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY
If it doesn't work, then you have to follow a few steps. All the required files can be downloaded using the link given at the end of the blog. So don't worry about the files.
First, you have to download the files and paste Arduino Library files into the proteus library folder. Your folder might be installed in the Programs folder by default. But in Proteus 8.9, there is no library folder there. ProgramData folder contains the library folder of Proteus Professional.

Hidden ProgramData Folder |
That's the folder in which you'll find your proteus library folder. In my case, it's located in /C: Drive.
By Clicking the folder, you'll get into this folder.
That's the folder in which you'll find your proteus library files. Click it.
Now, that's the folder we're looking for. Click this folder.
Now paste your Arduino library files into this folder. Restart your Proteus Professional software, and you are done. Now you'll see these library files in the proteus component section.
Now you can see your Arduino Library. Now you can open your schematic file and double click on your Arduino UNO library, and then locate your hex file given in the provided link folder.
Proteus Schematic
This circuit is designed using Proteus Professional 8.9. Lower versions of Proteus Professional can't open the schematic file.

The two logic buttons show the output values of IR-Sensors. At the output, IR-Sensors give 5 Volts or logic 1 when at rest. And when it detects something, it provides the output 0 Volts or logic 0. In this project, we are using 2 IR sensors. The first sensor detects the incoming vehicle and increments the count, and the second sensor detects the outgoing vehicle and decrements the count.
