I made a digital business card, it is like remote control in your pocket, it can automatically open all of your website and write all your business details on notepad.

Why i made this :-

In this digital era people are still using old business card or visiting card to introduce there business. So i was thinking to make a advance card which can show all of the card information in PC. The process i have used is very simple and easy to customize.

But why squid games business card :-

Actually, squid games is a famous web series, and the card used in that series was unique and well designed. Ao i used a reference of that series to make this card, i have shared the PCB design of the card so this is also very customizable according to requirements.

This is a PCB based Digital Business Card, it has USB interface to easily plug in and plug out. The card is based on theme of famous web series, which is Squid Games.

There is no need to connect battery or any cell to this device, it will take power itself from USB. This easy to carry business card can contain all of your details in your hand. The card can be customized with little bit of code knowledge.

Let's build it.

Supplies

Digispark Board
Squid Games Digital Business Card PCB
oldering iron

Step 1: What We Gonna Do

Firstly we will take Digispark Board, it has built in usb driver so it can be directly program with PC.

Because this has usb driver we can perform HID with it.

HID (HUMAN INTERFACE DEVICE) :-

The Human Interface Device Class (HID) is mainly used for devices that allow human control over a PC for an example, keyboard and mouse is human interface device, so human can write and click inside the pc.

Secret:- people also use as rubber ducky.

By using this HID feature, i made a digital business card PCB, the PCB looking beautiful because it has same look as the business card in famous web series.

The PCB for This project is sent by PCBWay, checkout there website to order PCBs.

Step 2: Installing Digispark Board

If you are programming Digispark board first time then you have to install the board in Arduino IDE.

Download the folder from my GitHub page from link given below.

GitHub :- https://github.com/vishalsoniindia/Digital_Busine...

Extract the folder, in the folder there is a text file.

Open the text file and copy the link given in the text file or also the link is given below.

Digispark Board link :- http://digistump.com/package_digistump_index.json

Copy the link and open Arduino IDE.

In Arduino IDE go to the files and then preferences.

Paste the link in additional board option, if there is other link then separate it by comma.

Click on ok, Now go to the Tools >> boards >> board manager, here type Digispark and install the board.

Step 3: Programming the Digispark Board

Find the code in the same folder which is download from GitHub.
Open the code and select board as Digispark 16.5Mhz.
Click on upload.
When you see connect your board below then connect Digispark board with PC.
After a sec you will see the code is uploaded successfully.

Customisation of code is very simple, just replace the website to your website, and text of note pad with your text. If you comment the line, it will no long exicute in code.
