Product description

Color:16x2 LCD

Introduction
LCD1602 is an industrial character type LCD that can show 16*2, i.e. 32 characters. The character generator ROM in the LCD module has already stored 160 different characters in dot matrix, including Arabic numbers, letters in low and upper case, and common symbols. for Arduino IDE, a built-in library LiquidCrystal can be called directly, and you don't need to write it, which is pretty convenient for beginners.
Its working voltage is 5V, and you can adjust the contrast via the 50K potentiometer. For the backlight, just connect pin A to 3.3V and K to GND, and then it will light up.

Note: You need to solder the Pin Headers before application.

Pins of LCD1602 and their functions:
VSS: connected to ground
VDD: connected to a +5V power supply
VO: to adjust the contrast
RS: A register select pin that controls where in the LCD’s memory you are writing data to. You can select either the data register, which holds what goes on the screen, or an instruction register, which is where the LCD’s controller looks for instructions on what to do next.
R/W: A Read/Write pin to select between reading and writing mode
E: An enabling pin that, when low-level energy is supplied, causes the LDC module to execute relevant instructions.
D0-D7: to read and write data
A and K: Pins that control the LCD backlight

Package Included:
-1 x LCD1602
-16 x Pin Headers

5.0 out of 5 stars Easy to hook up, easy to get working
By D. Michael McIntyre on March 3, 2018
After bashing my head with a display that was $4 cheaper, I swapped it for one of these. I used the library and some demo code from the SunFounder website. When I first powered it all up, I had the same garbage as on my previous display, but then it blinked, and lo there did I see before me a hello world! I had the display part of my code up and going in no time, and my display doesn't exhibit the weird interleaved addressing some others have reported. I hooked it up with four wires and no extra resistors, and it works like a charm.

Incidentally, the built-in character set did not have a degree symbol, so I made one.

// degree symbol
byte degreeSymbol[8] = {
0b00110,
0b01001,
0b01001,
0b00110,
0b00000,
0b00000,
0b00000,
0b00000
};
// create degree custom character
lcd.createChar(0, degreeSymbol);
lcd.print((char)0);
lcd.print("F");

5.0 out of 5 stars Unit works with UNO, NANO, MEGA etc. Lots of examples, works great
By Dr. Rogers JGT on February 4, 2020
After wiring to an Arduino UNO, MEGA. The SDA to A4 and SCL to A5, then +5 and Gnd, I turned on the unit and got a blue screen, no characters. It seemed to be a problem. After adjusting the LCD Contrast Variable Resistor on the bottom and the characters were clear. Both of my boards were adjusted to wash out the display.

Load the library using Sketch Menu, then Include Library, Add Zip file "LiquidCrystal_I2C_LIB.zip"

Test some example code using File, Examples, LiquidCrystalI2C. Looks very useful. Dr T.
