because my fans are 12 V and doubts I have are ;

* I will put 3 , connect them in parallel with the other, or goes in the F2 ULN2003A ? ... And third in the F3 ventiador ?.

* and all pins are spliced ​​1 to 7 and pin 1 ULN2003A ? ... I do not understand to do where you put pin1 disable that I have to do ?

Good is that there are several questions and I would be very grateful to you for help .

Hi!

Welcome Jose!

* I will put 3 , connect them in parallel with the other, or goes in the F2 ULN2003A ? ... And third in the F3 ventiador ?.


Use a pin to each fan.

* and all pins are spliced ​​1 to 7 and pin 1 ULN2003A ? ... I do not understand to do where you put pin1 disable that I have to do ?


Yes, all pins of control are in parallel.

The pin 1 is used to turn ON or OFF the fans. See the code here.

Best regards.
