Handwashing with Bolt

Introduction:

Due to COVID-19, we all have realised the importance of washing hands and how it is effective at keeping the virus at bay. It is recommended to wash your hands 10 times a day and for at least 20 seconds per wash. However, many of us forget to do so regularly as we are immersed in a work from home environment.This project is meant to help you remain healthy by reminding you to wash your hands.

Demonstration:

Connections:

• Connect the buzzer to the breadboard and notice the + sign on one end of the buzzer.(You can also identify the positive and negative end of the buzzer by remembering that the shorter leg is negative and the longer leg is positive.)
• Using 2 jumper wires, we will make the connection with the buzzer and the Bolt Wifi module.

• Connect the positive end of the buzzer to the digital pin 1 and connect the negative end of the buzzer to the GND pin.

NOTE:There is same voltage in the same column of a mini breadboard.
