Sensors decoded
Eight parts on reading the physical world honestly — pull-ups, analogue noise, calibration and knowing the difference between a broken sensor and a lying one.
Every sensor module is a small analogue circuit with a digital promise, and most beginner project failures are really sensor failures: a floating pin, an uncalibrated threshold, or a datasheet range that never matched the room. This track goes sensor family by sensor family and teaches the reading, not the wiring diagram.
