I ordered the Arduino Uno from Robotshop Inc. online. I also ordered the Getting Started with Arduino book but when I noticed that the order was “pending” for a few days (and I had order Express Post 2 Day Shipping), I called their Customer Service line.

The 4-Digit 7-Segment LED circuit that we will build with an arduino microcontroller is shown below. The segment A on the 4-digit 7-segment display connects to digital pin 9 on the arduino. The segment B on the LED display connects to digital pin 2 on the arduino. The segment C on the LED display connects to digital pin 3 on the arduino. Cnc plotter machine using arduino It is a cnc machine that are use to design any image or shape automatic by apllying login to view URL is like a robot in which we give only one command and it will plot any image. There are many application of cnc like cnc 3d plotter, cnc lathe machine, cnc cutter machine.

Apparently, the book was on back order so I cancelled that part of the order. Now I’m glad that I did because I found what looks to be all of the necessary “Getting Started” information online, for FREE at Arduino’s website.

By the way, the people at Robotshop Inc. were amazing. It was my own fault that I didn’t notice the book was on back-order when I placed the original order (not theirs) and they made the change to my order right away over the phone. So I want to give a shout out to them and publicly thank them for having excellent customer service.

So, today my Arduino Uno arrived by ExpressPost! Oh, the excitement! I felt a little like a kid at Christmas… I have to admit it was really exciting getting that package and opening it up. Now, the BIG surprise?! I was astonished by this…

The Arduino Uno is TINY compared to how I had envisioned it in my mind. I guess by comparison to some of the other Arduino boards, I thought it would be bigger. Check out the different models here. That Nano must be really small because my Arduino Uno can easily fit inside a small package of cigarettes container. In fact you could stuff two of them in a king size pack of cigarettes container.

Here’s the Arduino Uno:

Do I care? Heck no! The fact that it’s so small makes it so much more potentially useful for a variety of applications. I now see how people are able to use multiple boards in their projects!
