 MMBS PROJECT LOG

1) Ambient Temperature Measurement & Display 

Shoaib Aman     5518

Ehsan Rafique   5505

Mossadique Iqbal  5580

2)Seven Segment LED Dice              
 Usman Shahid   1849

Muzamil            5205

Saad Bin Ammar   5396

3) AC & DC Voltmeter(0V-30V)        

Ahsun Khan        4861

M. Owais Turk   4638

Shah Muhammad    3768

4) Temperature Controller               
Talha Farrukh     5199

Waseem Abbas   5210

Mustafa Mujaab 5184

Note: In addition to displaying the ambient temperature, u have to control it too.

Nothing difficult. Add two buttons to set (increase/decrease) desired temperature. If the ambient temperature is above the desired value turn on a fan if its below turn on a heater/ incandescent bulb. Well u dont need to interface an actual heater/bulb just light an led when temperature is high.

U will be displaying three things on the LCD. Ambient Temperature, Desired Temperature and Status of led(heater) and fan.

5) Kelvin, Celsius and Fahrenheit Display     

Muhammad Kaab            5597

Amir Jamal Siddiqui         5440

Note: Display the temperature in all three units. Higher the degree of precision, more the marks u get.

6) Bell Control System          

Zainab Qureshi  5441

Wajeeha Noor  5421

Note: In your project u should interface an RTCC(Real Time Clock Calender ) IC with the microcontroller. Save the bell ringing timings in memory. In main loop of your program u just need to check the current time and match it with your bell ringing times. If its a hit turn on the bell otherwise turn it off. U may use a buzzer in place of bell as it requires less interfacing circuitry or u may use a dc motor to ring an actual bell.

7) Tachometer        

Abid Ali Awan    5313

Sajid Akbar         5425

Hamid Iqbal        5622
Note: plus points for using Quadrature encoder. You can make one yourself on a transparency using this software

11) RGB Light Color Mixer     

Amir Raza    5419

Abdul Qadir Vadharia     5529

Ahmad Abdullah              5451
Note: Since u will be using RGB LEDs in your project there are three options u might consider.

1) No grayscaling. In this case u will be able to display 7 colors and wont require any driver IC (not recommended)

2) Combined Grayscaling using MAX7219. In this case u will be using grayscaling on red, green and blue colors individually and by that i mean that u will set the value of all channels of one color at the same time but u wont be able to set different intensity values of different channels of the same color. MAX7219 gives 16 levels of grayscale for each color so you will get 16*16*16 = 4096 colors.

MAX7219 is a constant current source switching ic so you will need common cathode rgb leds.(acceptable)

3) Individual grayscaling of all channels of red, green and blue individually using TLC5940. This particular ic provides 16 grayscaling(pwm) channels with 12 bit duty cycle (4096 steps) control. So by using this IC the maximum no. of colors that u can displays is 2^12 * 2^12 * 2^12 = 68719476736 colors. I suggest that initially u guys down scale (map) the 12 bit values to 8 bit values for ease of manipulation on an 8 bit microcontroller. This will give u 2^24 = 16 million colors.

Later on, if u have time, u may use the whole 12 bit duty cycle range... and if u are able to do so u will get full marks in the project!!!
TLC5940 is a constant current sink switching IC so u will need common anode leds to do the job.

(Strongly recommended)

P.S : I suggest u use Arduino as a microcontroller. U dont need to buy the Arduino. Just use Arduino's IDE for coding and when the hex file is generated burn it in an AVR (ATMEGA328, ATMEGA168 or ATMEGA8). Using the Arduino IDE for your project will make things simpler because it has a library for the TLC5940 and u will be working on a higher level of abstraction, rather than using the SPI protocol or bit banging to do the job.

12) Overheat Alarm                

 Muhammad Shoaib  5359

Yousuf Kamran 5402

Ammar Farooq  5477

Note: Stop screaming... sirf naam change kia he. Temperature Alarm sounds n00bish.

13) Goal Keeper Gun              

Shoaib Shaheen  5566

Hassan Aleem   5521

Ubaid-Ullah-Farooqi  5563

14) Traffic Light Signal             

Hamza Jadoon   5290

Samreen Batool   5306

Umm-e-Rida      5406
Note: Cross roads k liay banao with down counter. actually tmhe 2 hi signal banane hain or baqi 2 on ki copies hongi. down counter k liay MAX7219 use kar lena.

15) Combinational Lock           

S. Jawwad ul Hasan    5524

M. Kashir Ali       5681

S. M. Hassan Abbas    5535

 Note: must interface LCD and keypad

16) Prayer Time Reminder    

Rabia Kulsoom  5470

Waqas Nazar      5489

Rana Arqam       5667

 Note: U need to interface two things with the mcu; an RTCC (Real Time Clock Calender) IC and an LCD. The LCD will display current time and the Prayer Timings for that day. u will need the prayer timing database inside the rom of mcu. u may use a software 'Salaat Time' to get the prayer timing database of a particular city. The simplest format database that u can get from this software is CSV(comma separated values) format. U will need to write a little program in any language that would take the database file as input and process it to a format acceptable by the microcontroller. 

Integrating the prayer timing database of a whole year into the microcontroller will not be possible as we dont have enough memory in the pic16f877a to hold such a huge amount of data and in this case u will need interface an EEPROM (maximum available in cooperative is 512Kbit eeprom, which will give u an extra space of 64Kbytes).

I suggest that u initially integrate the database of one month in the microcontroller. Later on if u have time u may interface the EEPROM filled with the complete database. and if u are able to do so u will get full marks in the project!!! (but again, ofcourse u will have to do some intense coding on the pc side to get the database of whole year... in a form acceptable by the microcontroller)

17) Robotic Arm        

Abdul Rahman Meer      5493

18) Monochrome Bitmap Display     

Usamah Riaz      5525

Salman Jafri        5620

Abdul Wahab     5614

Note: Since u did not tell me the application of your led matrix display your self, i've modified ur project slightly... What u need to do is
i) Take any monochrome bitmap picture from your pc

ii) Convert it into hex array (bitmap to hex conversion)

iii) Put that hex array inside your code

iv) Burn the code in mcu and display that bitmap on the dotmatrix display.

U may use the johnson counter or MAX7219 to interface the matrix with your microcontroller.

Full marks chahiay to bitmap to hex converter khud banao...

19) Servo Motor Controller

Sarmad Jamal    5335

Shahzad Ahmed   5383

20) Pic16f877a based Calculator        

Areeb Minhaj    5446

Abdul Hafeez     5591

Iqbal Hussain Rajpar       5457

21) Digital Alarm Clock            

Muhammad Farooq Khan   5520

Muhammad Sohaib        5280

Raheel Anwar    5627

Note: u may display the clock on seven segments or LCD. Use an RTCC(real time clock calender) ic to get accurate time. Ur project must have set Alarm and set Time modes.

Project Proposal Format and Ideas for MMBS Semester Project

Project Proposal Format
Students from all 3 class ids of MMBS LAB are required to submit the Semester Project Proposals for approval. In your proposal you need to state the project title, group members and the description of project.
Project description should summarize the key idea/objective behind the project and how you plan to achieve the same using a microcontroller.
DEADLINE FOR PROPOSAL SUBMISSION IS 20th SEP, 2012 (THURSDAY). FAILING TO SUBMIT THE PROPOSAL ONTIME WILL RESULT IN MARKS DEDUCTION.
YOU ARE REQUIRED TO SUBMIT YOUR PROPOSALS(HARDCOPY, SINGLE PAGE) TO ME(ABDUR REHMAN) IN THE DSL LAB (OR TO SIR UMAIR IF I'M NOT PRESENT THERE).

NOTE
Keep in mind that it is a semester project, the purpose of which is to assess your understanding of the theoretical concepts of MMBS and your ability to practically implement these concepts. Please choose a project in which a microcontroller provides an optimal solution in terms of computation capability and cost. The project must not be so simple that it may be easily implemented by the jellybean logic ICs and not so complex(computation intensive) that its beyond the computation capabilities of a microcontroller. 
The project must have a practical application and it should be evident that a microcontroller's decision making ability and on chip peripherals were in fact required to achieve the task.
