Object Detection Using Lidar Module

The Object Detection Using Lidar Module project operates by combining precise distance measurement with mechanical rotation to scan a surrounding area. At the core of the system is the Arduino Nano, which coordinates the actions of the VL53L0X Lidar sensor module and a NEMA17 stepper motor driven by an A4988 driver. The stepper motor rotates the Lidar sensor through a controlled angular sweep, allowing it to measure distances at various points in a plane. The VL53L0X communicates distance data back to the Arduino Nano using time-of-flight principles via I2C, while the A4988 driver translates step and direction signals from the microcontroller into precise motor movements. As the scan progresses, the Arduino processes both the current angular position of the motor and the corresponding distance reading from the sensor. This information is then compiled and rendered visually onto a 128x64 graphic LCD (GLCD), allowing users to view a real-time spatial representation of the scanned environment. The entire circuit is powered through an integrated power supply switch S1 and assembled cleanly on a PCB utilizing Berg strips for modular connections, with onboard LEDs providing visual status indicators.
