Frequency Counter using Arduino Uno

I'm new to the Arduino and would like to build the Frequency Counter using Arduino (…) which is a great project but I have a few questions:

1 - For the LCD panel the article refers to a related article "Interfacing 16x2 LCD with Arduino (…) which shows the LCD part number as: JHD_162ALCD;  I'm in the USA, and I have not been able to source this part at all.  Can anyone provide a source for the part or an alternative equivalent part that would work?  If you can, please provide source name/website and part number.

2 - The first line n the sketch for the Frequency Counter project shows an #include that references "LiquidCrystal.h":  #include <LiquidCrystal.h>

Is the LiquidCrystal.h part of the Arduino IDE or is it a file I have to source from elsewhere?  Can you provide specifics, i.e. where to get the file?  Is that file specific to the JHD_162ALCD LCD or is it required for any LCD?  

Thanks for any assistance!

Hi Pete,

Sorry for the late reply, hope you are still willing to try out this project.

1. You can follow this page to get started with LCD Arduino interfacing. You can buy any parallel LCD display (16*2) and let us know about it. We will guide you here, if you get stuck somewhere. 

2. The header file #include <LiquidCrystal.h> is a default header file, you need not worry about it. You can straight away paste the code and complie it. Further you can also try codes from File -> Example -> Liquid crystal
