Arduino Tutorial – Make a Flex Sensor for Robotic Hand (Cheap and Simple)

In this tutorial, we will learn how to make and use a flex sensor.
We will control servo motor with a flex sensor.

Flex sensors are passive resistive devices that can be used to detect bending or flexing. The flex sensor shown in this tutorial is a flex sensor that decreases its resistance in proportion to the amount it is bent in either direction.You can easily make a sensor wider and longer depending upon your project.

Required Materials:
– Paper
– Flexible Cardboard or Plastic
– Pencil
– Aluminum Foil or Aluminum Tape
– Wires
– Solder or Glue Gun
