Dears,
I have experienced a lot of trouble in visiting electronics-lab site from my dial-up. I think it nearly takes ten times more time to load a web page than anyother site. Has someone else also experienced it? Whats the reason? ???
IRDetectors are much more costly then a green led .However a simple led (eg green or ret or else) can be used as an IR detector. Will somebody tell about its theory. I have not experimented it yet .
