Eric, my curiosity is killing me !

Won't the first circuit that u gave work?

How does the circuit u gave me work ?
why should i connect the circuit to pin#3 isn't just pin#2 and pin#25 enough?

what actually does the circuit do ?
why connect to pin#13 and
what is PB#1? is it a switch ?

 

hi john,
The circuit will work Ok for pin3 as planned.

Ive just drawn the pin2 part as the next step you are going to want to know as you learn.

Get pin3 working the transistor and LED, let me know, I can then explain pin2 function which can be used to drive a motor.

pin13 is for when you want your VB prog to read an external push button.

Does this explain it OK?

Remember: pins 2 thru 9 are ALL outputs you can call from your VB prog, use any pins from 2 to 9 that suits you.
Just call the correct pin from the VB prog. OK

 

does that mean that in the first circuit that u gave, i will not have to connect pin#2 ? right?

 

john,

Yes right!.

Remember: pins 2 thru 9 are ALL outputs you can call from your VB prog, use any pins from 2 to 9 that suits you.
Just call the correct pin from the VB prog. OK

Use either pin 2 or 3, it dosn't matter, as long as you call the pin from VB.
If you call 0 and 255 you will switch ALL 8 output pins 2 to 9.

EDIT: If you prefer, email me on my Yahoo address, you should have that from my earlier email to you.

 

ok i get that ! what does the IC in the 2nd circuit for?

and what all do u have to connect in the first circuit ? the pin#3 and pin#25?
-( its taking me a while to find all the parts thats why i dint complete it yet!)

Do you have yahoo messenger account?

 

can u send me Dllport.dll

 

hi,

This thread is now being answered as a 'one on one' by email.

is circuit#1 used to use the pin #3 and pin#25 as a switch to activate the motor using the 12 V dc ?
