Circuit Documentation

Summary

The circuit in question is designed to interface an Arduino 101 microcontroller with a VL53L1X time-of-flight distance sensor, an I2C LCD 16x2 screen, a red LED, and a resistor. The Arduino 101 serves as the central processing unit, controlling the LED and communicating with both the distance sensor and the LCD via the I2C protocol. The LED is connected to the Arduino with a current-limiting resistor to indicate status or provide user feedback.
