This kit lets you prototype a solution - a miniature multi-bay parking lot that uses four ultrasonic sensors, an ESP32-S3 microcontroller, and a live WiFi dashboard to show which spots are free. It's a hands-on IoT project that mirrors real-world smart parking systems found in malls, offices, and smart city deployments.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eBy the end of the 4-5 hour assembly, you will have a working four-bay parking model. Each HC-SR04 sensor continuously measures distance to a vehicle; the ESP32-S3 processes the data and updates an LED strip to show red (occupied) or green (vacant) beside each bay. Simultaneously, a web dashboard served over WiFi displays the real-time occupancy map on any browser-connected device. No external cloud service - everything runs locally on the microcontroller.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eInterfacing multiple HC-SR04 ultrasonic sensors with the ESP32-S3 and calibrating threshold distances for reliable vehicle detection\u003c\/li\u003e\n  \u003cli\u003eProgramming a deterministic slot-state machine that avoids false triggers and hysteresis\u003c\/li\u003e\n  \u003cli\u003eSetting up an ESP32 as a WiFi access point and serving a responsive HTML dashboard with live status updates\u003c\/li\u003e\n  \u003cli\u003eSoldering and assembling discrete components - resistors, capacitors, and a WS2812B LED strip - onto a prototype PCB for a compact, permanent build\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eESP32-S3 Dev Board\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHC-SR04\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWS2812B 4-LED Strip\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e470?
