Note:

  • Arduino's analogRead() maps voltage output (for seeeduino film 0V - 3.3V) to integers from 0 - 1023
  • We use Arduino / Sharp with 3.3 V instead of 5 V as in Sharp's specification

Min and Max Values for different conditions (always in TAG lab with daylight + lamplight)

Reflective Material min val max val
Black fabric 65 717
My palms 65 724
Spoon 12 720
Paper 2 715

→ reflective material does not really matter
