What if you want to show more output than a bunch of LEDs can handle? Sure, you could set up a bunch of LEDs to display numbers. But what if there was another way...
Character LCDs are super robust and great for output. Anything you can fit onto the 16 (lines) by 2 (rows) screen can be output by your code when you drop in the LiquidCrystal library, a collection of code that let's you add new functionality to your circuits.
We are going to re-create CIRC10. But instead of printing to a serial monitor, we are going to print to an external character LCD.
