This document discusses code for reading flex sensor values and controlling LEDs based on the flex sensor reading. The code initializes an analog pin as an input to read the flex sensor values, which range from 0-24. It then uses if/else statements to light different LEDs depending on which range the flex sensor reading falls in to.
