Summary

This circuit integrates an Arduino Mega 2560 with a VL53L1X sensor, two stepper drivers connected to two bipolar stepper motors, a two-channel 5V relay, and a power supply. The Arduino Mega 2560 serves as the central controller, interfacing with the VL53L1X sensor via I2C communication and controlling the stepper drivers and relay module through its GPIO pins. The power supply provides the necessary voltage and current to drive the stepper motors and relay module.
