Social Distancing Reminder

https://drive.google.com/file/d/1hOoOQ9lyPxblGcBaxsr9-aZIsq9Z5J-w/view?usp=sharing

Hello everyone, this is my first project on Arduino Project Hub.

My name is Krishna Srikanth, I am 9 years old. I am a student of MECHATRON ROBOTICS, New Delhi. I have completed a full fledged course on Arduino and electronics in just 2 months. I have always desired to become a scientist in ISRO, Perhaps i’m also taking these small steps at an early age.

In these tough times of COVID-19 Virus, I have made this super easy project Social Distancing Reminder which will help you maintain a distance of 1 metre with another person. This virus spreads rapidly with physical contact and air transmission upto 1 metre. This piezo electric buzzer will create a sound whenever the other person comes as close as 1 metre.

Looking forward to contribute more to this world by more innovative ideas.

Thanks!!

Stay Safe and Happy !
