Introduction: Smart City of Vukovar - Our View of Smart Living
This magnificent prototype of a smart city offers a solution in reducing the traffic jams on the road and around the parking lots, greater electricity savings and better use of a solar Sun power panels.
It represents a prototype of the real projection (look) of one part of the main road in Vukovar, Croatia leading toward another city in our region as well as the beautiful promenade along the bank of the river of Danube. It demonstrates of what a technological future should look like. By using all the sensors, IoT and high technology electronic boards, we are able to collect the information in real time, which allows us to more efficiently plan and implement utilization of the urban infrastructure as being the foundation of every “Smart city”.
My motto is: “We provide a solution for less pollution”

Step 1: Step 1: Getting the Material, Cutting and Gluing
The basis for the model design is a 4 mm thick plywood with its flyers to achieve a better and more solid structure. Connecting of all parts of the model will be achieved by using the wood glue.
The model is made from two parts. The basis of the model dimensions 750 x 720 mm will feature a promenade along the Danube River for which I used the Arduino Uno board, a photo resistor, infrared sensors and LED lighting. At the position of the upper surface of the load bearing part of the model, I created the basis for the main part of the model according to instructions. The main part of the model (detachable) will be 750 x 500 mm in size and will present the prototype the county main road in Vukovar. The cutting of plywood according to dimensions is done by an angle grinder. In the step 1, after measuring, cutting and connecting all the cut parts on the lower bearing structure, a 2 cm styrofoam is placed with a net in the Danube riverbed, which is strengthened and crossed by flexible tile glue, while in the main part of the model there is an artificial grass on the slope facing the promenade. Artificial grass is attached to the slope using the transparent silicone.
At the same time as the entire model is built, a solar tracker construction is made from wooden flyers. During the production of all wooden parts, all defects are removed, correction and adjustment is done.
In the 1 st step, after all modelling work, the design of the model is followed by painting according to the actual appearance of the road and the promenade in Vukovar.
These surfaces are first painted with the core colour, followed by synthetic enamel paint for the final appearance and strength. All the painting is done manually by brush or with a paint roller. After two final color layers, a decorative granulate is applied in the place where the solar Sun tracker will be attached to the main surface. For strengthening the granulate I used the super glue.
Step 2: Step 2: Programming
In the 2 nd step, Arduino codes are being programmed for smart lighting, smart parking, smart traffic lights and a solar Sun tracker. In addition to programming, drawings are made on the 3D printer, brackets and traffic lights are printed for the intersection on the main road. Except programming, all other necessary parking spaces and accompanying facilities on the main road are made.
Step 3: Step 3: Finishing and Final Touches
The 3 rd step includes the installation the installation of the Arduino boards and all other electronic components for the final appearance of smart city model.
Step 4: The Code: Smart City Lights
SMART CITY LIGHTS along the river of Danube which use the photo resistor, infrared sensors, led lights, and Genuine Arduino UNO board. The main principle is that the LED lights are on with a reduced brightness, but as the person approaches every light, the infrared sensor activates the program which turns on the light much brighter. As you leave, it comes back to reduced brightness. At this point of our Humanity, in the 21st Century, we have to look for a new ways and solutions on how the save more energy to avoid power outages and to bring electricity to rural areas on this Planet. Our smart city lights offer tremendous savings in electricity consumption.
Step 5: The Code: Smart Traffic Lights
SMART TRAFFIC LIGHTS are very adaptive to the current traffic. By using the infrared sensor placed in the asphalt before the traffic light, it senses the movement, and according to the current situation regulates the traffic. Smart traffic lights let us avoid situations where the driver would have to sit in the car and wait for a green light to come up when there is no one around at the intersection. By using this type of the traffic lights, we can drastically reduce traffic jams. For this project I used Genuine Arduino MKR 1000 board.
Step 6: The Code: Smart Parking
SMART PARKING uses an infrared sensor to determine whether here is an empty parking space available and how many are left at the parking lot. As the vehicle approaches the parking, the sensor gets activated showing available spaces on the LCD display, opens the ramp and enables the entrance into the parking lot. As soon as the vehicle enters the ramp goes down to its normal position. The same procedure is when vehicles leave the parking lot. For this project I used Genuine Arduino MKR 1000 board.
Step 7: The Code: Solar Sun Tracker
SOLAR SUN TRACKER uses a photo resistor to adjust the angle of the solar panels according to the strongest source of the Sun light. This way of tracking the Sun light gives us the opportunity to increase the percentage of using the Sun energy which is stored in a power bank for later use and distribution of electricity to the city lights. For this project I used Genuine Arduino MKR 1000 board.

What an awesome model! Do you think that you can add a simulation website of the Smart City of Vukovar? You might want to add another instructable for that. :)

Thank you for such a positive comment. I haven't thought about it, but it sounds great. I might get into it this summer. My hometown municipality officials implemented the smart parking in downtown Vukovar as a result of this project in the beginning of this year. Have a nice day.
