16×2 LCD is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. But the most used one is the 16*2 LCD, hence we are using it here ...

Notice that the contrast control (LCD pin 3), instead of using a typical 10K potentiometer, uses an LM334, which ensures a constant current of 200µA to ground (so the contrast does not need to be ...

The PCB provides a 16-pin header compatible with standard 16x2 LCD modules, and should fit many of them within the footprint of the board if the headers are soldered at the top of the module. Note ...
