About the Project
For this project, I made a GUI for a parking lot. The project ran on my computer and also on a Raspberry Pi. In the GUI, we can see it has five parking lot indicators. Lot 1, for example, has a green background, meaning there is one parking spot available, as indicated by the one within the box. On the other hand, lot 2 has a red background. This means there is already a car parked there with zero spots available. The state of the lot will change based on the pressure sensor value that will then be transmitted to the computer and shown on the GUI using a publisher and subscriber method that communicates over MQTT.
The video demonstration shows the feedback of the circuit connected to the Raspberry Pi and the GUI running on the computer. Due to not having a pressure sensor, this is simulated with me moving the GPIO pins for a specific lot location from ground to VDD. It simulates that a vehicle would have parked on top of this pressure sensor and returned a high input value, which will change to a red lot with zero spots available to show that.
