How many power supply pins are there in LCD?
Character lcd’s Pin names and functions In these 14 pins, 8 are data pins(From DB-0 to DB-7). Three are lcd control pins RS(Register Select), R/W(Read-Write) & En(Enable). Two are lcd power pins Vcc(+5v) Vss(Gnd). The last pin is lcd contrast pin(V0).
What is I2C module for LCD?
I2C is a synchronous, multi slave, multi master packet switched, single-ended serial bus. ie. multiple chips can be connect to the same bus. I2C uses only two bidirectional open collector or open drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL), pulled up with resistors.
What is LCD 20 * 4?
A 20×4 LCD means it can display 20 characters per line and there are 4 such lines. In this LCD each character is displayed in 5×7 pixel matrix. This LCD has two registers, namely, Command and Data. This is standard HD44780 controller LCD.
What are different LCD pins?

Why I2C is used in LCD?
I2C_LCD is an easy-to-use display module, It can make display easier. Using it can reduce the difficulty of make, so that makers can focus on the core of the work. We developed the Arduino library for I2C_LCD, user just need a few lines of the code can achieve complex graphics and text display features.
What is 16×2 LCD display?

What is the function of pins RS and RW of LCD?
The RS pin, which is short for Register Select pin, is used to select either Instruction Register when it is LOW or Data Register when it is HIGH. The RW pin or the Read / Write Pin is used for selecting Read Mode or Write Mode. When RW is HIGH, read mode is selected and data is read from the register.
What is 16×2 LCD I2C?
This is a 16×2 LCD display screen with I2C interface. It is able to display 16×2 characters on 2 lines, white characters on blue background. Usually, Arduino LCD display projects will run out of pin resources easily, especially with Arduino Uno. And it is also very complicated with the wire soldering and connection.
