What This Unit Covers

Read digital touch sensors correctly, accounting for active-low hardware logic, and use them as reliable software limit switches.

Convert raw potentiometer voltage into engineering units using Range.scale() for absolute positional feedback without a homing sequence.

Sample and compare color sensor channels to identify alliance game elements reliably across different field lighting conditions.

Review the sequence and goals here, then resume at your first incomplete lesson.
