The following questions are designed to make sure that you understand the physics im plications of the experiment and also to extend your knowledge of the physical concepts coveredYour report should answer these questions in the noted section in a seamless man 1181'. 1.) [Theory] Explain what \"turn on\" voltage means as it relates to semiconductor diodes, specically noting what will be observed in the case of an LED. What is physically occurring in the diode as this voltage is crossed. Note: You may need to refer back to Lab 3 and apply your knowledge of semiconductor physics to adequately explain. 2.) [Procedure] In the apparatus section there are two different transistors mentioned. Look up the pin out of both transistors and comment on how your wiring would change if you had used a TIP-410 transistor. 3.) [Discussion] Why is it important to put a break in the \"for 100p\" when a certain current threshold is reached? What would happen to the circuit if you allowed the Arduino to sweep the full 5V (or even further)? 4.) [Appendix] Add additional comments to code you used for data collection, your com ments should explain what each line is doing and which portion of the circuit the code interacts with. Submit this commented code as an appendix in your lab report
