    The connections are OK, the anode is common, the cathodes goes to the 4094. When the leds should light? When something ferrous / non ferrous is detected?

                        Are the same resistance or are different. I know that they are 10k but are the same material? or are metal film and the others ceramic?
                        The question is, can i use any of this? Is the same.
                        Thank you.
