Documented Code
No code was provided for the Arduino Uno R3 microcontroller. Typically, the code would be responsible for initializing the analog inputs, reading the values from the flex resistors, and possibly performing some form of signal processing or decision-making based on the sensor inputs. Without the code, the functionality of the microcontroller in this circuit cannot be fully described.
