hi,
i am designing a project to take the output of the fuel guage and convert the analog reading to digital by using adc...i hav desgned it such a way that if input vol is 12v the ouput is 5v.(one 15k and 5.1k,output across 5.1k),nw if the input is more than 12v hw do i protect my uc frm this..can anyone suggest me a circuit...??
