Design Project Requirements
Your Project and Power Point Presentation needs to be ready by Wednesday's Class Session (3/04). Here are some items to include in your Power Point Presentation:
What problem your device is solving
Include System Block Diagram illustrating the solution or innovation
BOM (Bill of Materials)
Explanation of Core Embedded Subcircuit and associated circuits (reference System Block Diagram in discussion)
Detailed circuit schematic diagrams
References (Circuits, Circuit Theory, textbooks,and websites)
Remember to have fun with your design project and be creative! You must bring in a working prototype of your Design Project and demonstrate it in order to receive full credit!
Lab Notebook
If you haven't done so, turn in your lab notebook for final review by the instructor.

DC Motor Controller Lab Update
The program on page 103 for Example 4-4 has been "remixed" to work properly with the relay. Also, the plug-in power supply for the MDE 8051 trainer doesn't have sufficient sourcing current to operate the small dc motor. Therefore, a separate DC power supply is required to operate the dc motor. A 3V DC power supply shall be used to operate the small dc motor along with the remixed software for next week's (2/17) lab. I'll provide the lab write-up along with the remixed software source code on 2/17.
Lecture Notes
Here's Chapter 5 "8051 Addressing Modes" part 1 lecture notes.
Homework Assignment # 5 (due 2/17)
Write out the questions with your answers
 | Review Problems pgs 112 & 122 (all questions on both pages) |
| Review the following wiki and answer the following questions |
a) draw a new circuit schematic diagram using the circuit on page 127 (Example 5-16) showing a voltage divider consisting of a 10K resistor (R1) in series with a 10K potentiometer (R2) wired to port P2.3. The 10K potentiometer should be wired as rheostat (See Sketch03.jpg) as reference.
b) Explain in a paragraph how the 8051 can be used as a replacement microcontroller for the Arduino in the Evil Bottle application.

I hope the application of I/O interfacing is somewhat cleared based on the lab performed in Wednesday's (1/27) class. All sorts of cool gadgets and devices can be created quite easily with a uC, particularly the 8051. Now for next's weeks assignments.
Blue Box Required
For the remainder of the class, bring your Blue Box. Small I/O interfacing projects will be assigned for the next 2 wks of class
Chapter 4 Lecture Notes
Here's the first part of Chapter 4 on I/O port programming. We'll wrap up the unit with a discussion on I/O Bit Manipulation Programming next week (2/3) after the exam.
Exam 1
For preparation of Exam 1, here's the Study Guide.
Homework Assignment #4 (due 2/3)
A) Design For Empowerment Article.
Design For Empowerment is a concept put into practice by artists and some engineers whereby creativity and innovation can be accomplished by embedded intelligence within the in-animated object they are creating. To illustrate how this creative class are adding embedded intelligence within their work, read the article by William Gurstelle titled "The DIY Chip" to get a perspective on one key concept of Design For Empowerment via Physical Computing. After reading the article, answer the following questions. Write out the questions with your answers!
B) Answer the Problems on page 107 Section 4.1: 8051 I/O Programming. Write out the questions with answers
C) Prelab 1:Designing a Small DC Motor Controller
To assist in understanding how a microcontroller can connect with the "physical or real world" for the 2/3 Lab session, draw the circuit schematic for a small dc motor controller. Using the circuit schematic diagram shown on page 103 of the textbook, replace the 74LS04 Hex Inverter IC and buzzer with a transistor relay - motor driver circuit. The following document can be used in referencing the transistor relay-motor driver circuit. In addition to the providing a circuit schematic diagram, generate a BOM (Bill Of Materials) for this Prelab assignment as well. NOTE: In order for you to complete the 2/3 lab, this circuit must be available for review by the Instructor.

I hoped you see how the 8051 microcontroller port pins can be simulated using Keil uVision Debugger/Simulator Tool. Great work in the lab. Keep it up. Also, download the uVision software on your own desktop PC or notebook and work through the examples in the lecture notes as well as in the book to reinforce the programming concepts. Now, for next week's exciting class assignments.
