ft232 avr code
@sn_burki,
you can start with atmega16 or atmega32. Try using BSD parallel port porgrammer and AVRStudio for assembly, winAVR for C. But if you know 8051 then why to AVR?. Better go for some 16bit or 32 bit chips withhigher capability.
first you decide which microcontroller you want to study. But go for an 8 bit microcontroller in the beginning. So try to find which one is suitable and if your friends know some 8 bit microcontroller take help from him. If you are interested in AVR then you can use the following link...
I wanna learn AVR
avrfreaks is the best one. It is a good forum where you can get reply for any questions you ask. Here I collected some important links
http://avrmicrocontroller.googlepages.com/tutoriallinksforAVRmicrocontroller.html
Start with atmel datasheet,post problems in avrfreaks...
winavr
go through the example codes given in some books.You can refer this link too
http://avrmicrocontroller.googlepages.com/introductiontoAVRmicrocontroller.html
Read the headers and sample codes given by winAVR documentation.

I have done 7segment interface with AVR microcontroller. Here is the link
http://avrmicrocontroller.googlepages.com/7segmentLEDinterfacewithAVRtutorial.html
But how many 7segment are you using. Why you use Proteus for that?

pwm with 555
if you are using potentiomenter, then you require just one potentiometer and a diode with 555 astable multivibrator circuit

seven segment
fading occurs due to variation in power supply. Use a good power supply like SMPS
http://www.geocities.com/njbibin/robo7b.html
see buffer also require a power supply and the amplification is just current amplification and everything depends on the main supply voltage
Bibin...
AC TO DC
this circuit is just R and C parallel, since diodes ckt wont work. What is the specifications of the AC and DC voltage. Here is a schematic of a power supply circuit

use normal recifier circuits

555 delay on circuits
I think you have a monostable circuit of IC555. If you want to understand the working of that IC go through this link

are you using microcontroller or parallel port. If you are using parallel port then here are some links for interfacing motor and keypad
