Hi All ,
i have built a circuit that connect pic16f84a 74ls47 and a coomn anode seven segmant.
i have a aproblem now that all the inputs of the 74ls47 gives 1.3 volts , i don't why.
for that reason my pic ports that connected to the 74ls47 is also 1.3 volts , even if i removed the pic IC .
i'll load the photo of that schematic and please tell me what's wrong.
thank you
