Understanding Flex Sensor
Flex sensors, also known as bend sensors, are a type of resistive sensor that can detect the amount of bend in an object. They are commonly used in robotics, prosthetics, and other applications where the angle of an object needs to be monitored. Flex sensors are made up of a conductive material that is sandwiched between two layers of plastic. As the sensor is bent, the resistance of the conductive material changes, allowing the angle of the bend to be measured.
Interfacing Flex Sensor with Arduino
Interfacing a flex sensor with an Arduino is relatively straightforward. The flex sensor is connected to an analog input pin on the Arduino board, and the Arduino is programmed to read the voltage on the pin. The voltage on the pin is proportional to the amount of bend in the sensor, so the Arduino can be programmed to read the voltage and calculate the angle of the bend.
Programming Flex Sensor with Arduino
Programming a flex sensor with an Arduino is relatively simple. The Arduino can be programmed to read the voltage on the analog input pin and calculate the angle of the bend. The Arduino can then be programmed to take action based on the angle of the bend. For example, the Arduino can be programmed to turn on a buzzer when the flex sensor is bent to a certain angle.
Flex Sensor and Servo
Flex sensors can also be used to control servo motors. By connecting the flex sensor to an analog input pin on the Arduino board, the Arduino can be programmed to read the voltage on the pin and calculate the angle of the bend. The Arduino can then be programmed to control the angle of the servo motor based on the angle of the flex sensor. This is a great way to create projects where the angle of a servo motor is controlled by the amount of bend in an object.
The first part is the active sensing element, which is typically composed of a conductive material like carbon or silver. The second part is the substrate, which is typically a flexible material like polyester or similar polymers. The third part is the protective coating, which is typically a thin layer of material like polyurethane or similar polymers. The fourth part is the connector, which is typically a metal or plastic connector that connects the sensor to the circuit.
Interfacing Flex Sensor with Arduino
Flex sensors can be interfaced with Arduino to measure the degree of bending or curvature. The Arduino is connected to the flex sensor using a voltage divider circuit. The voltage divider circuit is used to measure the resistance of the flex sensor. The voltage divider circuit consists of two resistors, one of which is the flex sensor and the other is a fixed resistor. The voltage at the junction of the two resistors is measured using the Arduino’s analog input pin. The voltage is then converted to a digital value using the Arduino’s analog-to-digital converter. The digital value is then used to calculate the resistance of the flex sensor.

Flex Sensor
A flex sensor, also known as a bend sensor, is a type of resistive sensor that changes its electrical resistance when it is bent or flexed. It consists of two contacts having no polarity, a conductive ink and a phenolic resin substrate. When the sensor is subjected to mechanical stress, such as bending or curving, the arrangement of the conductive elements is altered, resulting in a change in the electrical resistance along the sensor’s length. The degree of bending or flexing directly correlates with the magnitude of the resistance change, and this change in resistance can be measured and interpreted electronically.
Interfacing Flex Sensor with Arduino
In order to use a flex sensor with an Arduino, a 10 kilohm resistor is connected in series. As the two contacts of the flex sensor have no polarity, the 10 kilohm resistor can be connected on either side. The other contact of the flex sensor is then connected to the Arduino 5V, and the other leg of the 10 kilohm resistor is connected to the Arduino ground. This creates a voltage divider circuit, where the output voltage changes as the resistance of any of the components changes. In this case, the 10 kilohm resistor is a fixed resistor and its resistance cannot be changed, but since a flex sensor is a nonlinear, flexible resistor, it can be used as a flexible potential meter. By bending the sensor, the resistance can be changed, and this way different voltages can be generated. The output voltage can then be read using an Arduino analog pin.
Programming Flex Sensor with Arduino
In order to program the flex sensor with an Arduino, a program needs to be written that reads the voltage from the analog pin and converts it into a meaningful value. This can be done using the analogRead() function, which reads the voltage from the analog pin and returns a value between 0 and 1023. This value can then be used to calculate the resistance of the flex sensor. The resistance can then be used to determine the degree of bending or flexing of the sensor.
Flex Sensor and Servo
Flex sensors can also be used to control servo motors. By connecting the flex sensor to an Arduino analog pin and writing a program that reads the voltage from the analog pin, the resistance of the flex sensor can be determined. This resistance can then be used to control the angle of the servo motor. By bending the flex sensor, the resistance changes and the angle of the servo motor can be adjusted accordingly.
Well, the advantage is that you can easily attach the flex sensor to any surface and you can easily use it for your project.
Interfacing Flex Sensor with Arduino
In order to interface the flex sensor with Arduino, a divider circuit needs to be connected to the Arduino’s analog input pin. The circuit diagram for the same is given below. This circuit diagram allows the Arduino to read the analog voltage from the flex sensor.
Programming Flex Sensor with Arduino
Once the circuit is connected, the next step is to program the Arduino to read the flex sensor. To do this, the Arduino IDE needs to be opened and the following code needs to be uploaded to the Arduino board. The code starts by defining the Arduino pin and the lock pin. Then, in the setup function, the serial communication is activated at a baud rate of 9600. After that, the pin mode function is used to set the flex sensor as an input. In the loop function, the flex sensor is read using the analog read function and the value is stored in a variable. Finally, the sensor value is printed on the serial monitor.
Testing the Flex Sensor
Once the code is uploaded, the flex sensor can be tested. It is important to note that the flex sensor should be bent slowly and smoothly, as sudden and hard bending can damage the flex sensor.
Attaching Flex Sensor to a Surface
The flex sensor can also be attached to a surface such as a wooden sheet or a metal sheet. To do this, the flex sensor needs to be soldered to two wires. Care should be taken to not apply too much heat while soldering, as this can damage the flex sensor. Once the two wires are soldered, the flex sensor can be attached to the surface. The advantage of this setup is that it allows the flex sensor to be easily attached to any surface and used for projects.
