I made a circuit using lm2917 and lm3914 to get LED RPM
i got 2 problem
1- after connecting the circuit with 12V power some LED's light ( it must not light as it light when freq increase then they start light one by one )
2- when i increase my car RPM LED's of 2nd ic lm3914 don't respond .
i made this circuit 2 times so i am sure i didn't made and wrong connection
can i get any help ??
