One of my best projects, the Answering Door Bell was initiated by the chairperson of our school. Though first prototype was made by our ATL incharge, Mr. Hirak Biswas, I am taking the project further. This simple device displays a message to the guest on your behalf if you are busy at that moment. This project was showcased at the Make Tomorrow For Innovation Generation (MTFIG) National Showcase, New Delhi (2018) and AIM (2021)
Problem statement
While having a conversation with our chairperson, Mrs Bhanumathi Neelakantan (aged 83), we came to know of a very common problem suffered by aged people – many a times they are unable to timely attend their guests at the door .
