Tutorial: Creating a Digital Device for Door Opening Monitoring

Welcome to our tutorial on creating a clever digital device to monitor door openings using a digital desktop calculator and a magnetic switch. Not only will you have control over access to the room, but you'll also be able to add an extra level of interactivity with this invention.

Materials needed:

• Digital desktop
• Calculator
• Magnetic switch
• Power source (AA battery)
• Connecting wire

Interesting Fact:

Magnetism in Modern Technology Have you ever imagined that the power of a simple magnet could be used to create smart digital devices? From mobile phones to personal computers, magnetism is often a hidden force that contributes to the operation of our modern technology. This once again demonstrates how simple principles can be transformed into complex innovations in today's digital world.

Connect one wire from one pole of the magnetic switch to one pole of the equal button. 

Connect The Other Wire Of The Magnetic Switch To The Other Pole Of The Equal Button.

 Press the button on the digital desktop calculator to initiate a new operation, such as adding 1 + 1. Approach the magnet to the magnetic switch. Observe how the digit displayed on the screen of the digital desktop calculator increases with each approach of the magnet and displays the correct result, 2 in this case.

Identify the suitable location for mounting the magnetic switch on the door. Ensure that the surface is clean and dry. Attach the magnetic switch to the door using adhesive or screws.

At the conclusion of this tutorial, we'd like to share with you an interesting and amusing fact about modern technology and innovation.

Funny fact:

With the advancement of technology, all sorts of creative and unexpected inventions have emerged. For example, did you know that in Japan there exists a hotel entirely managed by robots? From receptionists and cleaning staff to housekeepers and waitresses, robots handle all the heavy lifting! Perhaps in the future, our door monitoring devices will even be able to program their tasks autonomously and take a break to recharge their batteries, so to speak. Nevertheless, technology never ceases to surprise us with its innovations, and we're excited to see what the future holds!

With that, we encourage you to explore and experiment with creativity in the world of technology. You never know what innovative and amusing ideas might emerge in your inventing process. Thank you for following along with this tutorial, and we wish you the best of luck in your future projects!

Monitoring door usage Once the device is installed and functional, it can be used to monitor how many times the door is opened. To identify the number of openings or who has entered and exited, observe the digits displayed on the digital desktop calculator and take notes or use a recording program if available.
