3.1.1 Inputs and Outputs

5. Unchecked, 0, not present

6. Checked, 1, present

7. It would have opposite reactions

9. 43 to 5000

11. 1521

12. 1360

14. Switching the wires into the opposite positions.

15. When the reed switch touches the electromagnet it gives out power.

16. Normally closed.

18. The light shining means the photo resister is closed.

19. More resistance = more light

20. Reverse the program.

21. Having it normal then it will be utilized .

1. Examine the wire diagram on the mini switch and describe how the diagram relates to the concepts of normally open and normally closed.
The normally closed side of the mini switch makes it so that the switch completes the circuit at all times, making it a closed circuit.  ___ _ ___
The normally open part of the switch makes it so that you must press the switch to close the circuit. __ / __

2. If computers only understand digital signals, then how is a computer able to interpret the analog signals coming from the interface?

Computers use the simulations of the analog inputs to produce digital signals to approximate their analog counterparts.

3. Why does resistance decrease as the NTC Resistor becomes warmer?
As the NTC Resistor gets warmer, the current will be increasing. To keep the same voltage, the resistance must decrease.
