My invention is a Real-Time Monitoring System for Disabled-Only Parking Spaces. It detects vehicle movement using HC-SR04 ultrasonic distance sensors installed in three locations, including the parking lot entrance. This data is managed primarily by an Arduino Nano RP2040 Connect board and is ultimately used to display the parking space status intuitively on a Flutter application screen. I used a Breadboard to connect the sensors and the board, and leveraged the BLE (Bluetooth Low Energy).
