Project Overview
This group project involved designing an absolute optical encoder disk, implementing IR-based sensing for 3-bit sector identification, instrumenting an Arduino for real-time data capture, and analysing rotational speed, angular resolution, bidirectional detection, and error sources such as vibration, misalignment, and light leakage. Includes full experiments validating accuracy across speed ranges.
