Arduino uno Flex Sensor

This project demonstrates how to use a flex sensor with an Arduino Uno to measure the bending of the sensor. The sensor's resistance changes with bending, which is read as an analog input by the Arduino. The measured value is then displayed on the serial monitor.

Components Needed

• Arduino Uno
• Flex Sensor
• 10kΩ Resistor
• Jumper Wires
• Breadboard
• Power supply 12 v

Block Diagram

Hardware Wiring Explanation:

Connect the Flex Sensor to Arduino Uno:

Connect the flex sensor and resistor to the Arduino Uno as described in the circuit setup section.

Monitor the Output

Open the serial monitor with a baud rate of 9600.

Bend the flex sensor and observe the serial monitor output displaying the sensor values, which should change with the bending.

Applications

Notes

Ensure the flex sensor is correctly connected to the Arduino Uno and powered.

The resistance of the flex sensor increases with bending, resulting in a lower voltage reading on the analog pin.

Adjust the code if necessary to map sensor values to specific ranges based on your application.
