I followed your instructions and getting error: I2C device not found on address: 0x3C

Result of the i2cdetect -y 1:

00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

Could you give me a tip where to look for a source of the problem?

Can you show the command you were trying to run when you got the error?

I'm sorry, It realized that it was a problem with my GND line, so Issue can be closed.
