Smart Trashbin metal detector with coin reward... need help

There is possibility the problem would be the inductive proximity sensor. I thought it is goods because when I testing this with only 1servo motor the servo rotate but the pins is directed to the Arduino , the GRND, 5V, and SIGNAL but it when I add another servo I got a problem now. So I don't think I a problem with Inductive proximity sensor.

clearly specifying all details means

@xarina_onlyme

but the pins is directed to the Arduino

which pin (which io-pin number) is connected to what?

@xarina_onlyme

So I don't think I a problem with Inductive proximity sensor.

depends on the proximity sensors internal circuitry

If it worked with one servo
but it does not work with two servos it is very likely that the battery can't deliver enough current or the battery is already exhausted.

Do you have a digital multimeter?
