Flex Sensor

The Flex Sensor project utilizes an Arduino Nano to measure and monitor the bending or flexing of a flex sensor. This project is useful in applications where the degree of flexion or bending needs to be measured, such as in robotics, prosthetics, or human-machine interface devices.

Components Needed

Circuit Diagram

Circuit Setup

1.Connect Flex Sensor to Arduino Nano:

Connect one terminal of the flex sensor to the A0 analog input pin on the Arduino Nano.

Connect the other terminal of the flex sensor to the GND pin on the Arduino Nano.

Optionally, connect a resistor in series with the flex sensor for voltage division if needed.

Instructions

1.Circuit Setup:

Wire the flex sensor to the Arduino Nano according to the circuit setup.

2.Code Upload:

Connect the Arduino Nano to your computer using a USB cable.

Open the Arduino IDE and paste the provided code.

Select the appropriate board (Arduino Nano) and port from the Tools menu.

Upload the code to the Arduino Nano.

3.Testing:

After uploading the code, open the serial monitor.

Observe the flex sensor values displayed on the serial monitor as you bend or flex the sensor.

Applications

robotics: Measure the degree of bending in robotic joints for precise control and movement.

prosthetics: Monitor the flexion of prosthetic limbs to adjust movement or trigger actions.

Human-Machine Interface: Use flex sensors in input devices for gesture recognition or motion tracking.

Notes

Ensure proper wiring and connection between the flex sensor and the Arduino Nano.

Calibrate the sensor if needed to adjust for different flexion ranges or sensitivities.

Experiment with different resistance values or voltage division setups for optimal sensor performance.
