Okey my friend , thank you for your patience and for your helps
Today is enough for me ;
i'm working about this project from 9 o'clock to now.
I think , it's time to make my brain free.
And one last question ; i don't know that you are interested in integrated circuits; if you are ; i want to ask something.
I have 2 op-amps LM358 and i learned that , the maximum supply current for LM358 is 600mA . I have a power supply with 6-9-12-15 adjustable ; and it says , it can give a current of 2.5A
So, if i connect it to my op-amps , do they blow out ?
Thank you .
