Questions from Optional Project
In this picture, both the red (the "no" light) and the green (the "yes" light) are lit up...but when I unplug the wire from pin #3, one light will turn off while the other stays on...this is how it simulates a 'decision maker'...you ask it a question, pull out the wire, and it will give you either a yes or a no
1. Did you find that your LED cathode was easy to recognize?
Yes the cathode was the shorter leg
2. Why do you think the first logic probe isn't very good?
Because it didn't
3. Was the second logic probe that much better than the first?
It did not draw its power directly from the source it was testing, so it therefore gave a better readout
4. What is the largest decimal number that can be represented by a 6 bit binary number?
63
5. Write the decimal numbers 5, 23, 87, and 132 in binary.
101, 10111, 1010111, 10000100
6. Why does the 7-segment readout produce "funny" symbols for inputs to the decoder of 10 to 15?
Because it only has seven available spaces, and the numbers 10-15 require more than those 7...so it creates different patterns for those numbers
7. Draw the schematic of an opto-coupler wired to control a 120 motor.
8. What specifications do you think are most important to understand when buying opto-couplers?
The amount of power it will be able to handle, maybe its reaction speed
