i'm wanna command a 12 volt relay with an LED (EB004)
the LED "D2" when it's lightened it's 5V so i have to convert 5V TO 12V and send it to RELAY so the relay is actually commanded by the LED "D2"
should i use a REGULATOR 7812 to convert the voltage ? will it work ? the picture below will explain what i want but it's not circuit i want how can i modifie it ?
PLEAZE HELP ME i have two days to find the solution
