Review the datasheet for the ATMega328P. Provide a description of each pin of the DIP and explain how each pin is used to interface with the microcontroller. 

Include the following:

• Type of signal (voltage, current, analog/digital, etc.) that would be associated with each pin
• Current/voltage ratings of each pin
• Whether or not each pin is considered an input, output or neither. 
• Discussion as to why this level of detailed understanding is critical to an engineer as opposed to a hobbyist that may be using the Arduino
