Story

This is a great project to teach your kids the importance of cleanliness & washing hands properly in the current times. This project turns the LED red when you start washing hands & will turn green once twenty seconds are complete thus reminding you to wash hands for twenty seconds & do not keep the water running while washing hands. Remember, in the midst of one global crisis, let's not worsen another.Maker : @devd_31 The circuit is made out of @arduino.cc uno board, an infrared sensor & a RGB led.
