  "account": "In a village without street lighting, the darkness at night posed significant safety hazards. The author, a CSE student, aimed to develop an affordable, automatic street light system that responds to darkness and natural light. Utilizing an ESP32 microcontroller, an LDR for light detection, and Flask for backend management, the system functions in a straightforward loop: sensing ambient light with the LDR, making decisions based on a preset threshold, and controlling an LED or relay to turn the light on or off. The ESP32 transmits data, including light readings and status, to a Flask server over Wi-Fi, enabling remote monitoring. The author emphasizes the project's practical value, as it turned a personal inconvenience into a functional solution and provided practical experience in integrating hardware and software for IoT applications.",
  "summary": "Why I Built This I grew up in a village where street lights simply didn't exist. Once the sun went down, the roads turned pitch black — and that wasn't just inconvenient, it was genuinely unsafe. People struggled to move around at night, and I personally ran into this problem more than once myself. That frustration is what pushed me to build this project. I wanted a low-cost, automated street…",
