The FlexiForce single element force sensor acts as a force sensing resistor in an electrical circuit. When the force sensor is unloaded, its resistance is very high. When a force is applied to the sensor, this resistance decreases. The resistance can be read by connecting a multimeter to the outer two pins, then applying a force to the sensing area. In this tutorial, you will going to learn on how to display the voltage level on 2×8 LCD and light up the LED based on the voltage level as the different force exerted to the Flexiforce Sensors(A201).
In this tutorial, you will going to learn on how to implement and use the flexible bend (for SN-FLX-01 and SN-FLX-02) by using BBFuino and SK28A. The setup and the source code shared at here will result the voltage display on LCD as you bend the flexible sensor.
