Servo Motor with Potentiometer and LCD with Arduino: SP-LCD-1

In this video, we learn how to control the angle of a servo motor using a potentiometer (variable resistor) and display the angle on an LCD1602 or LCD2004 with an I2C module that has four wires.

This is code 1, where we need a breadboard to distribute power from 5V to the potentiometer, servo motor, and LCD. Details have been explained in the video.

Here is the code for use without a breadboard.
