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

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.

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

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)

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
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...
