Simulating the Movement of Dancing Grass

Hey, do you know a kind of plant that changes its state with its temper? In fact, as early as more than 200 years ago, Swedish botanist Linnaeus named it "Hedysarum gyrans", which later scholars classified into the genus “Dancing grass”.

Gypsophila is a plant that lives in subtropical Asia.At present, it is mainly distributed in China, India, Nepal, Bhutan and Sri Lanka. Dancing grass looks very ordinary:Slender stems, oblate green leaves and purplish red flowers.Everything seems so ordinary.But once it is exposed to strong sunlight,stimulated by a higher pitched sound or high temperature,We can see the rapid rotation of its leaves with the naked eye.And the rotation is regular. So in this tutorial we will use Arduino, temperature sensor and light sensor to simulate the movement mechanism of dancing grass under the action of high temperature and strong light.

• With the help of temperature sensor we can read the temperature of the environment
• With the help of light sensor we can read the light intensity of the environment
• After receiving the strong light and high temperature, the movement command is transmitted to the steering gear to complete the corresponding movement.
