Story

Hey Guyzz...

In this pandemic I trust everybody is at home staying safe.

I made a new project named Gentleman Touchless Doorbell.

watch the whole video to make this project at home.

In this covid time when any guest arrives at you door guest will stand infront of this gentleman and a sensor senses the guest then doorbell rings and this gentleman will remove his hat welcomes the guest.

This is a great project which can be made at home easily and can be installed.

If you like this project respect it.

Give me suggestions so I can improve it or any feedback you want to give to my YouTube channel.

link is : https://studio.youtube.com/channel/UCaXI2PcsTlH5g0et67kdD6g

Also you can give me suggestions on "What I made next project.?"

Steps to make this project:

1. Gather components like Arduino, servo motor, pir motion sensor, cardboard, breadboard, jumper wires, any drawing, speaker etc.

2. Make gentleman at separate paper and stick it on the cardboard.

3. The part of gentleman you want to move make it on separate paper and stick cardboard behind it.

4. Stick PIR sensor on the gentleman from behind.

5. Stick servo motor shaft on the hand of gentleman or any drawing part you want to move.

6. Stick servo motor.

7. Stick arduino, speaker etc back of cardboard.

8. Do connections from circuit diagram

9. Upload the code and adjust the sensitivity of PIR sensor according to your need.

10. Install it on the door or wall of your house.

Your project is ready...!!!
