Something else is wrong here.
With a 1kOhm resistor across 5V supply, the current would be 5mA not 5A (=5
Volts/1000 Ohms). Not enough to fry either Resistor or IC. There's a similar
application shown in the book - Getting Started with Arduino. See the attached
file.

Must have been something else. Circuit works now, (but row driver still dead?)
Will close when complete system works.
