To improve on the original idea, I have created a reference business card. Here is a computer render of the design: I wanted to show every common component I could think of, and how they relate. Often when zoomed all the way into a digital design, you ca ...

Arduino RFID Card Reading

Finally! It’s been about 3 months since my last arduino tutorial – I’ve been keeping busy as usual. I’ve been working on this one for some time. I got the parts months ago, made an outline a few weeks ago, prototyped the circuits and wrote the code last week, and did the filming over the last few days. [box type="note" color=" #202020 " bg="#ffbb00 " font="verdana" fontsize="14" radius="20 " border="#000" f ...
