______________________________________________________

Common Q & A

Q1. does all assignments get sent to you by email, not on Canvas ? 

A1. I use Canvas for a few purposes:

1. At the beginning of the class, I use it as an intro for the class, and set up a link to this web page.

2. Syllabus quiz

3. Announcement when new assignments are posted

4. Grade Book (grades are posted 1 week after due date)

After that, our class web page takes over for Assignments details, Resources, etc. 

Sending assignments by email is faster, especially when Canvas is down (there is no middleman).

Digital Lab Kits

Digital Lab Kits will be provided to you in class, you use it to do lab in class and at home. 

The unit is assigned to you until we finish the final lab, then you return it to me in the class room.

Common Q &A

Q0.  I am not able to save or downloads Assignment #2 files @Docs.Google. Could you send me the Assignment #2 file.

A0.  Once you open up the file, do:

File/Download/Microsoft PowerPoint(.pptx)/ Filename: assign-02-ecer103-YOURfirstName-Lastname.pptx

then edit your file in the downloaded folder.

email to Ui.luu@gccaz.edu attaching your edited PowerPoint

______________________________________________________________

Q1.I have spent quite some time troubleshooting it  and got it to work perfectly, so I will attach my part of the assignment and turn it in.

Just curious, what did you do to make it work? Correct wiring error?

A1. For me, the problem was that I didn't plug the parts in all the way so it might be that caused the trouble with it. So I just unplugged everything and plugged it back in and make sure they are all the way in their spot. It works!

Additional Practices (Optional: 0 point / Report NOT required)

(Optional) Build & Test AND Logic

1. draw schematics with pin assignments, 

2. build circuit based on schematics

3. Take a photo of circuit board

4. Connect to the "Power & I/O" test board. Run 4 test cases, take 4 photos

5. Put test data next to the truth table.

5. Put in the PowerPoint, save filename as 120-bonus-assign-03-FirstName-LastName (for your own record, NO report is required) 

_______________________________________________

(Optional) Build & Test OR Logic

_______________________________________________

Review the following microPointer: Example of Combination Logic below, then do Assignment #4

Guided Tour for the beginner / Assignment #5 (courtesy from Stephen Kurelowech)

(Note: If you are new in building circuits, it is beneficial to compare notes with your teammate, you still have to build your own circuit & take your own pictures)

Warnings

If you submit my original PowerPoint or "Guided Tour" as your report, your total score will be 0.

______________________________________

Building Circuit / Secret of Success : 

1. Follow Logic Diagram closely

2. Each wire has 2 connections, Triple check each connection before adding the next wire.

3. "Despacito" / Go Slow : The slower you go, the faster you will get your circuit working.

Design a Lethal Security System using SOP Method

Video (12:28): Getting started with Lethal Security System

(Note: The video was made for Assignment #6 Fall2020 Class, It mentioned Build & Test circuits. Last semester, majority of beginners can NOT make the circuit to work, because it's a little more complicated than the newbies can handle, and they cried! So, I decide to make the Build & Test part 100% optional, only do it because you have time and want to challenge your building & troubleshooting skill)

Common Q & A

Q0. After reviewing the feedback, I know what is missing, can I resubmit for partial credits?

A0. No. Each assignment is treated like a test, follow instructions closely and give it your best shot; I only grade it once.

__________________________

Q1. Why is b + b' = 1 ?

A1.  Consider 2 cases:

case 0: b=0 then b'=1:       0 + 1 = 1

case 1: b=1 then b'=0:      1 + 0 = 1

Boolean Algebra Power Point at the top of this page covers this info + other worthy items to review
