Trying to build an IR project

[financecatalyst]

Ok then, thanks for all your help upto now. I think I need little more of it.

I have searched the internet and tried to understand the principle behind IR communication. I have made my very first Tx & Rx with that. It's not working as it should do.
It's not a completely dead scenario as I do see voltage fluctuations on the TSOP2438 IR Receiver module output pin when I switch on my transmitter and when I switch my Tx off it goes stable. I also looked into my webcam and could see the IR Tx LED glowing.

I attach my code here to have some feedback on any mistakes I am making. Thanks again.
