AVR-Chat

If your DC motor is small (less than 600 mA), you can use 
L293D for the driver. It is widely available here :)

And about the TIP35, i dont think it is a darlington. Its 
Hfe is only 25.  And i dont think it is wise to uses NPN 
transistor because the output pin of an 8051 (AVR too?) is 
initially HIGH. I prefer the IRF540. It is said from the 
datasheet it can be used for high speed switching 
applications. I used an IRF540 myself, but as a high 
current switch. It works well. Another option is TIP125, 
it is a PNP BJT darlington. This is also widely available 
here :)

About the timer 1, give me time to learn AVR again. Or i 
will ask my friends at campus ;)

Regards,
Irfan.
