Sensory Replication Using Arduino – Week 2

After deciding what nature based inspiration source to use for our project, attention was shifted to how we though the scene would play out with the all the inputs and outputs in a real-life scenario.


So as the car would come closer to the hedgehog, the animal would sense it was getting closer through the intensification of the vibrations it could feel in the ground. Next the hedgehog would curl up into a ball and shake, retreat away from the road and possibly shriek.


So, identifying the scenario led to the development of what we needed to sense and then output based on that sense. First was the sense of vibration (main input as the hedgehog can’t see the car. Then our output would be the hedgehog shaking and then making a noise as if it was scared.

To do this we would need these specific electronics to do so:

  • Piezo Vibration sensor (input)








  • Vibration Motor (output)

DC vibration micro motor

  • Speaker (output)


  • Step motor (for movement if we want added complexity)
