Hi there,

Recently I participated in a science fair which was held in an engineering college and I stood first in that fair

A science fair is a competitive event, hosted by schools worldwide. The distinguishing characteristic of a science fair is that project entries employ the scientific method to test a hypothesis.

Science fairs are not exhibits or mere displays of projects. Students present their science project results in the form of a report, display board, and/or models that they have created. Science fairs allow students in elementary, middle and high schools to compete in science and/or technology activities. The goal of a science fair is for students to answer a question based on a hypothesis. Students often work on science fair projects in addition to their school work. Therefore, most science fair entries are usually modified versions of existing experiments. Display boards help communicate the nuances of a project to science fair judges, visitors, and other entrants.^[3]

Science fairs also provide a mechanism for students with intense interest in the sciences to be paired with mentors from nearby colleges and universities, so that they can access to instruction and equipment that the local schools can

I made an automated dustbin and a digital thermometer.

With the increase in population, we have an increase in the garbage around urban areas. Here we propose a smart dustbin that operates automatically to help solve this issue using IoT and sensor-based circuitry. Usual dustbins require to be opened by pressing foot against its lever and then throwing garbage. Also, a person needs to keep track when it is full so that it can be emptied and does not overflow. Here we propose a smart dustbin that does all this by itself. Our system consists of a sensor in order to detect human clap signal and on a clap of foot tap, it opens automatically without anyone needing to press its lever. The dustbin opens automatically when it receives the signal and closes its hatch.
