This is lab 1 of 9 in the course, Fundamentals of Mechatronic Sensors.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Understand the voltage dividing properties of a potentiometer. 
  2. Calibrate the output of a potentiometer in terms of angular displacement.
  3. Determine an encoder's pulses-per-revolution.
  4. Examine non-quadrature, X2, and X4 decoding.
  5. Calibrate the output of an encoder in terms of angular displacement.
  6. Observe the effect of low sampling on the accuracy of measured data.
