I still struggle on reading datasheets.
I found this site:

That helps you determine the base resistor to put the transistor into saturation. I am struggling to figure out where they get the values from the sheet.
1. I see where they are getting hFE but this is the min value. Why did they chose 110 for the example?
2. How did they determine a 770mv VBE from the datasheet?
3. How did they determine a 250mv VCE from the datasheet?
