Arduino interfacing with Flex sensor
1. Flex sensor
Flex sensors are passive resistive devices that can be used to detect bending or flexing. The Flex Sensor patented technology is based on resistive carbon elements. As a variable printed resistor, the Flex Sensor achieves great form-factor on a thin flexible substrate. When the substrate is bent, the sensor produces a resistance output correlated to the bend radius the smaller the radius, the higher the resistance value.

2. Component needed in this project
In this
project we are just measuring the analogue voltage of flex sensor and giving it
out put in a led to show change in voltage while bending the flex sensor.
In this project we would need component which are
described below.

3. Arduino interfacing with Flex sensor
Interfacing of flex sensor could be done with arduino
with simple configuration which is shown below. And in this project we would
see that brightness of the led connected to the digital pin of the arduino will
change according to the banding in the flex sensor. And print that analogue voltage of the flex sensor on the serial monitor of arduino software.
The
connections are pretty easy, see the image above with the breadboard circuit
schematic.
Note: - Don’t
you forget to connect the 10k and 1k resister with the circuit other wise it
may work wrong and you project would fail.
