It is a great improvement and good start @starstrings01. And I pray and hope that you get the best out of the automation training as you were promised.

Also regarding the use of LCD with Arduino, I observed that it's a 16x2 LCD display screen as we have bigger LCD like the 20x4 too, to reduce the number pins the LCD takes on the Arduino board and also the use of lots of jumpper wires and variable resistor for adjusting brightness and constract of the LCD, I would suggest u use or checkout I2C LCD driver module which makes it possible to use just 4 pins to interface your LCD with Arduino board which consists of 2 power pins and 2 communication pins easily.

I'm very much open to assisting you in this journey when the need arises. And probably use it as a way of repaying u for the love and support you bestowed me and more.

I wish u success and more developmental growth towards this path 👍.
