Hi All..

I dont know what about Mesut, But All of you
did not convince me!!!!
I think that the photo Transistor With BUILD IN DIODE
Is BETTER, Because One PIN Goes to VDD, One Is Floating,
And One Is The OUTPUT... Any easyer than this ??
Also, saves money and time to study...
this is my suggestion for you Mesut, surely not for
studying purpose, but for industrial, because
you will not study anything from connecting it.

transmitter anyway, should be an IR LED, connected to
your outputs' logic circuit (5V or 12V to 0v) with
resistor. most logic circuits can light a led.(15mA)
the most used band is about 35KHz to 50KHz, with TV's,
If they find it right, I'm sure that they know more than
me...

Goodluck
bye
