2. The summary statement describes a concern about turn-off time, but it is important in this specific case? Is it the principal issue in the project? If this is an issue, then you need to indicate how - quantitatively – whether it is indeed a problem, and the approach to solving it. 3. For question 1 (Q1), you will need to reference the spec section that has the characteristics of the output pins, not the power supply current draw. Check section 30, and table 30.1. Q1: In addition to referencing the relevant section of the data sheet, should have some text that says, in effect, “These specs indicate that the drive capability is ….” 4. For Q2: “An Arduino output can, technically, deliver up to 40mA…” What is the condition of this spec? Is there a guaranteed output voltage for this condition? 5. The chain of reasoning for Q3 can be clearer. Some of the transistor spec calculations seem to mix various conditions that will not be in the circuit. You need to relate how the conditions in the circuit with your design choices for R’s are consistent with both the AT Mega and the transistor specs. design and check of a motor drive interface for an Arduino.
