DIY Home Security - New Video: • DIY Simple PIR Motion ...
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

@Mert Arduino and Tech Hi, when I tried this, my servo motor keeps moving in circles at 0 position. Note: I did not the aluminum part with the cardboard yet, I wanted to test out the flex sensor itself. Could that be why?

just map the results between 12 & 48 then? servoposition = map(flexposition, 0, 1023, 12, 48) servoposition = constrain(servoposition, 12, 48)

@insideouteyes5572 5 жыл бұрын

I may be out of the line here, but I think the graphite on the paper works as an electron transmission medium, when it is bent, the amount of surface area for electron transmission changes, and that changes the resistance. But as I said, I am presumptuous

@DudeBoerGaming 4 жыл бұрын

You are right. Graphite is conductive and in essense acts as a resistor. The more graphite, the less resistance and less sensitive.

i know that what are you trying to do. but, i don't understand that when you bend your flex band, how it will be creating close path between aluminium contact? and change in resistance is too far from your device.
