what is the I2C address of Arduino UNO board and how to modify i2c address

[system]

I got it, if we specify address in Wire.begin(0x23); then 0x23 will be I2C address or it will take 127 I2C address by default.

What sort of question is this? The address would be 0x23. What else would it be?

I want to make it in between 0 to 31 number as an I2C address.

0x23 is not the same as 23.

Respected Sir

Thanks a lot Sir.
I got it. It is working for my implementation. You are mind blowing Sir.

Thanks & Regards..
