LIDAR-ENABLED MICRO DRONE WITH PROXIMITY EFFECT

Micro drones are increasingly used in various applications such as surveillance, inspection, and research. However, traditional drones are expensive, require large operating space, and are prone to collision risks. This paper presents the design and implementation of a micro drone with proximity alert using LiDAR technology. The system integrates an Arduino Pro Mini, F3 EVO flight controller, LiDAR sensor, buzzer, and LED indicators to detect obstacles in real time. The LiDAR sensor measures distance and alerts the user through varying buzzer frequency and LED blinking based on proximity. The proposed system offers a low-cost, lightweight, and efficient solution for safe navigation in confined environments.
