The dipslay that you find in market is SPI based but because of so many wire connection in SPI based display it become hard to work with because even any one of wire connection is loose then display wont work so to make it ease I used SPI to I2C converted and solder te pins to I2C driver so you can easily use the display

Yes , In fact both i2C pins are inter connected on arduino board . so you can use th SCL and SDA pins of arduino to connect both RTC and Display I2c driver

Sir, can I use a single I2C bus for both RTC and LCD display? In the Fig.5 we are using separate I2C connections for RTC and LCD display.

Sir,
“Fig. 5: Connection for SPI to I2C converter display”

As per the schematic we are using I2C lines from the Arduino Uno. I don’t understand what is SPI to I2C converter.
