The kit from Microcenter that I purchased did not come with a base board like the Vilros kit from Amazon, so I had to make my own baseboard. I knew I needed to construct my new baseboard on a material that would not cause cross circuit interference. So I chose to construct my board of Plexiglass material.
The first constructed version of the project yielded a functioning LCD that was not displaying the expected results. The LCD screen was working, but not showing any recognizable characters.
I was not sure if the potentiometer that came with the Vilros kit was able to control the voltage for this project. The hardware requirements list called for a 10K potentiometer, and I was not sure if the kit supplied one met that requirement. So, I purchased, what was listed as a 10K potentiometer from Microcenter. The new potentiometer did not have leads attached to it, so I had to solder some leads to the new potentiometer.
The new potentiometer did not work at all with the system. In fact, I had no visible reaction to the LCD screen at all.
So back to the drawing board...
After a good nights sleep, time to get back at it..
And after much internal deliberation (I just new I had the board wired correctly), I decided to recheck my wiring setup using a magnifying glass. I learned that my regular glasses were not enough. Upon rechecking my wiring with the magnifying glass, I discovered a slight error in lead placement. I corrected that error and eureka!, there it was..
Yes, it worked as advertised. Now just a little bit a code play with a Hello to the class..
and a change in the timer display speed change..
And this is a demonstration of the potentiometer and it's applicable use in television and computer monitors. The potentiometer would be used to not only adjust contrast, but different color levels, brightness and other features.
Thanks for reading my project blog.
