16×2 LCD with I2C configuration

Here’s the LCD I’ve started with for my data display.

I got it on ebay for a couple dollars.

After working on the 12-wire configuration for a while, and never figuring out how to shield the noise that was goofing up the letters, I found an example with the I2C configuration.

Life. Saver.
