What is I2c/TWI in Arduino?

|What is i2c or TWI? i2c/TWI(Two Wire Interface) is a type of interface used with MicroController it is used to make the wiring of the modules or Output/Input Easier because it only uses 4 Wires to Connect. those Wires Are Vcc|Gnd|SDA|SCL
What is SDA  & SCL? In  only two wires are used for Data Transmision But It is not Simillar to The Rx and Tx lines. the two Connections Are SDA(Standard Data Line) And SCL(Standard Clock Line) SDA(Standard Data Line):-This line transmit the Data Signal (In Binary mode of transmission) To The I2cChip And the Chip Calculate the Data with The Clock Line Signal SCL(Standard Clock Line):-this maintain the time for the data signal and assit the I2c chip to calculate data signals
Where to connect the SDA & SCL line? Every MicroController Board Have It SDA & SCL on different places like

Resistor Calculator (Advance)

Enter the Resistor Value like, '120000' for 120 K Ohms

-- or --
Enter the Bands to decode
Band One: BlackBrownRedOrangeYellowGreenBlueVioletGrayWhite Band Two: BlackBrownRedOrangeYellowGreenBlueVioletGrayWhite
Band Three: BlackBrownRedOrangeYellowGreenBlueVioletGrayWhiteSilverGold Band Four: GoldSilverNone

Fill out either form, to find out the value of a resistor, or the color bands for a value of a resistor.

TFT Game by Areeb

if you are fond of doing paint and want to make something related to that. So Here is the project for you. This Project is a Painting Software Based on TFT touchscreen
This project have Many Feature like:- Various Color Choices Can Change pensizeDifferent games layout like | i}tic-tac-toe | ii}Word Game | ii}Complete LOGO Different Pen Shape like |i}line | ii}Circle | ii}SquareHelp Button For New User 
  Material needed:- Arduino UNO(can use mega also)Arduino TFT touchScreen Sheild (buy it here)How To Make :-This Project is Very Easy to make Just You Have To Fit the TFT shield on the Arduino And Then Just upload the code  /* * Arduino TFT Paint * by Areeb-ur-Rub * FaceBook Page:- */// Don't Change These information #include<Adafruit_GFX.h>#include<MCUFRIEND_kbv.h>MCUFRIEND_kbvtft;#include<TouchScreen.h>#ifdefined(__SAM3X8E__)#undef__FlashStringHelper::F(string_literal)#defineF(string_literal)string_literal#endif// These are the pins for some typical…
