1. To upload the code in Node MCU firstly, connect the Node MCU with your Laptop or PC via Micro USB cable as shown below: 

2. Now, select Node MCU board in Arduino IDE: Go to tools <Board<ESP8266 boards< Node MCU 1.0(ESP 12E module).

Note: If Node MCU board is not visible then refer Lesson-2.

3. Then, again go to tools and select the Port as shown below:

Note : If the port is not coming,then check if the driver is installed in your PC or not.

4.Now, click the upload button and when the uploading will be finished then you will see uploading finished written below:

Working:

After the uploading is finished, try testing your code.When you will move a car in front of Entry sensor the the servo will move.Now,move the car to any of the parking slot then the parking slot servo gate(servo) will open and you can park it and when the place is occupies then it will display the space occupied.Two servo motors are used as entry and exit gate, so whenever the IR sensor detects a car, the servo motor automatically rotates from 45° to 140°, and after a delay, it will return to its initial position. Another three IR sensors are used to detect if the parking slot is available or occupied and send the data to Node MCU
