Two resistors are set in series with the power source from the Arduino board of 5V. If each resistor is 1000 Ω, then 2.5 mA will flow through the circuit and A0 will measure 2.5 V. This is a voltage divider. A0 measures the voltage from row 13 to row 23 (GND).
Note: Each verKcal row is connected on the back end (indicated with yellow line for rows 3, 13, and 23) In the top bar, the enKre + and – line are connected on the back.
Full circuit is highlighted in yellow for clarity.

The second resistor is replaced by the spoon, for example, measuring the raKos of voltage across the known resistor and the unknown, it is possible to determine the spoon’s resistance.
