Good Fernando , first thank you for your great work I really admire is like a person has bothered to share such an expensive work in all aspects ... I wanted to ask you a question because I 'm riding my ferduino and 'm riding circuit assembly according RECOMMEND :
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 .
Regards.
