excellent! Primary school invention “automatic dry wet rubbish separation box”
Have to say, garbage is already part of our daily life, but for many students, dry garbage is still wet rubbish, and often stupid. Not long ago, Huizhou Nanyin Primary School Experimental School Zhang Heng invented a “automatic dry and wet slip separation box”, not only without contact, but also to flip the garbage, but also automatically induces dry, wet rubbish, automatic investment Send it to the garbage storage room.
Huizhou Nantan Primary School Experimental School Student Zhang Heng: My invention is a dry wet rubbish automatic separator. Its main function is to cover itself. Its identification is the 5 to 50 cm of this ultrasonic sensor, itself Identify that someone will flip directly to identify dry wet rubbish.
As the saying goes, the inventions from life, Zhang Heng Tong, are also commented on his careful observation during the epidemic.
Huizhou Nanshen Primary School Experiment School Zhangheng: During the epidemic, the garbage bar downstairs should be handed over, I feel so unharitage, it is easy to infect the bacteria, so I think of this automatic flip, and I can distinguish it Wet garbage trash can.
Creativity has, but to be truly implemented, Zhang Heng can don’t have fewer efforts. “Automatic dry and wet spam separation box” is composed of a box, a control panel, a steering gear, an ultrasonic sensor, a raindrop sensor, a wire, and a tie. Structurally, Zhang Heng uses waste wood to make housing, realizing turning waste into treasure; circuit, using a raindrop sensor, achieving dry wet waste classification; in addition, the most important point, at the teacher’s finger, all The programming is written by Zhang Heng himself, but in this link, Zhang Heng also encountered difficulties.
Huizhou Nangtan Primary School Experimental School Student Zhang Heng: I have a bit difficult to edit this coverage, and I have to relate to ultrasonic waves, and I have to be related to this cover and have to be related to this raindrop sensor.
In the end, with the help of the teacher, Zhang Heng continued to debug, finally told. Among the 19th Huicheng Youth Science and Technology Innovation Competition, Zhang Heng wesks the first prize of innovation projects with a dry wet waste separation box, and the three prizes of innovation projects in Huizhou Youth Science and Technology Innovation Competition. In fact, Zhang Hengneng completed this invention, and he himself loved programming. Brought a lot of changes.
Wuxi Nantan Primary School Experimental School Teacher Section Qi: After learning the programming, the child’s logical sense will be stronger, and it will be more careful, because the programming is some symbols, but it is wrong with a punctuation or letter, the program cannot run Some children feel better about the symbol, I suggest that you can learn.
