SunFounder IIC I2C TWI 1602 Serial LCD Module Display for Arduino R3 Mega 2560 16x2 https://www.amazon.com/dp/B019K5X53O/ref=cm_sw_r_cp_api_glt_fabc_RT12B0DY1Z3FNBH00VZY?psc=1

Looks like this has a PCB that changes the parallel to serial communication.

Probably amazon. I dont know in which country you live.

Oh, it looks like they have an “I2C to parallel” adapter dongle thing for this display that also has the contrast potentiometer. That’s nice.

Lots of good projects can be completed with those components. It's a good kit.

My only criticism would be that the LCD screen doesn't appear to have the accompanying I2C module that makes interfacing with the Arduino so much easier. Here is an example of an LCD with the I2C: https://www.amazon.com/SunFounder-Serial-Module-Display-Arduino/dp/B019K5X53O

Usually the I2C boards cannot be purchased just one at a time. You can buy two or more: https://www.amazon.com/HiLetgo-Interface-LCD1602-Address-Changeable/dp/B00VC2NEU8

You can get by without it and wire up the LCD per this tutorial: https://docs.arduino.cc/learn/electronics/lcd-displays but it uses a lot more wires, a pot, and a resistor where the I2C module just needs four wires.

My guess is the components are also going to come without the header pins soldered on...do you have a soldering iron to complete that task?

the black board is the actual adapter it self u can find it by searching for 1602 lcd i2c adapter on youtube, amazon etc

This is great because a 16x2 LCD display has 16 pins to connect. Plus you gotta throw a potentiometer in there to control contrast. It's easy to not know what to do (especially as a beginner).

I tend to just use the I2C module at this point. It has everything built-in and only 4 pins to connect leaving more room to connect other things to your arduino.

Here is a link for a great tutorial when including the module. It needs it's own library as well (which is provided in the tutorial) http://robojax.com/learn/arduino/?vid=robojax-LCD1602-I2C
