Detailed explanation-1: -Is the flex sensor analog or digital? The output of the flex sensor is analogous in nature, but you have to add an additional resistor and construct a voltage divider with the flex sensor for analog output. If you want to get a digital signal from the sensor then you need to add additional circuitry to the sensor.

Detailed explanation-2: -A flex sensor has a range from about  10K to  35K, that means it won’t give us a full 0-5 volt range (or 0-1023 analog value). Try to use the serial monitor below to find out what analog value you will take while you bending the sensor. It supposed to be between 700 to 900.

Detailed explanation-3: -A Flex Sensor or Bend Sensor is a device that measures the amount of bend or angular deflection by resistance change. A Flex Sensor is made up of a variable resistive surface. The sensor resistance is varied by bending the sensor. The resistance is directly proportional to the amount of bending.

Detailed explanation-4: -Working Principle This sensor works on the bending strip principle which means whenever the strip is twisted then its resistance will be changed. This can be measured with the help of any controller. This sensor works similar to a variable resistance because when it twists then the resistance will be changed.
