Inputs
According to the logic design, ultrasonic sensor and button are used as input of our project to transfer the physical data of distances into digital data, and further generate some interaction between people and the “cat” on the screen.
Theory
- the Doppler Principle
Ultrasonic sensors mainly use Doppler Principle. The crystal vibrates to emit high-frequency ultrasonic waves beyond human perception. If there is a motion in the region, the reflected wave frequency will fluctuate slightly, that is, the Doppler effect. In this way, objects in the lighting area can be judged to move, so as to achieve the purpose of controlling the switch.
