Dear Rashu,

Its good that you took the decision to start in small steps.

Going by the I/O summary that you prepared, I should say you have an aptitude for hardware and hence embedded software must be fun to learn and implement.

I am not sure about your budget - but if you can stretch it to 99 USD, then the Cygnal kits are the best bet. You can start programming from day one. As an individual importing could be a pain and you can contact ,

Hynetic Electronics, Bangalore,
Ph:080-6614627 / 080-6524577.

They are the dealers for Cygnal in India. Ask for an entry level kit and they should guide you from there.

Else go for the P89c51RD2 which is a flash MCU and you can download the free programming software FlashMagic from www.esacademy.com. This runs on WINDOWS. On the contrary if you use p89c51, then you need a programmer to program it. If you can manage to get one, then start with the p89c51.

Start with the tutorials on this page if you have not done so already.
