How To Find Unknown I2C Addresses Several Ways

After struggling to get a 128x64 OLED display working over I2C, I learned many things about I2C addressing including:
-There are 7-bit and 10-bit addressing schemes
-There is no 8-bit addressing scheme, but some vendors improperly provide 8 bit addresses
-There are a few shortcuts to finding out what the real I2C address of a device may be
-As a last resort, an I2C scanner can be employed to locate all valid devices on the bus and report their addresses

This is a video of my journey!
