Resistor registry

Exact resistor assignments have not been chosen. This page is the single location for the future mapping between piece identities and electrical acceptance ranges.

Sensor family	Identities needed	Nominal values	Acceptance ranges
Road	Players 1–4	TBD	TBD
Building	Settlements for players 1–4	TBD	TBD
Building	Cities for players 1–4	TBD	TBD
Land	Land/resource types, including desert as applicable	TBD	TBD
Robber	Presence only	No resistor identity needed	Digital debounce TBD

The 10kΩ value in the BOM is the reference resistor for the divider, not a chosen piece identity.

Information to record when assigning values

Each entry will need identity, applicable sensor family, nominal resistance, resistor tolerance, measured ADC/resistance band, and calibration context. Whether different sensor families can reuse a resistor value remains to be specified. Values must be distinguishable within every family where they can appear.

Reserve unambiguous empty and unknown classifications. Do not assign a valid piece near an open-circuit boundary or rely on a single exact ADC value. Account for component variation and repeated real contact placement, not just ideal resistor calculations.

Calibration relationship

Use calibration to measure known pieces, then establish non-overlapping acceptance bands across the intended operating conditions. A reading outside an accepted band remains unknown even if one nominal value happens to be closest.

Registry versioning and where calibrated values are stored remain open. Examples in diagnostics are illustrative and must not be copied into this registry as final assignments.
