Solution

It seems like you are encountering an error while trying to scan for available I2C devices on the bus. The error message you mentioned,

Could not open file /dev/i2c-1: No such file or directory

Could not open file /dev/i2c-1: No such file or directory

, indicates that the I2C device file is not being recognized, what type of i2c model are you using
