Many spurious errors are actually power issues. Powering the Arduino is an often overlooked, but a very important part in the effective use of the device. It lies near two surface mount capacitors. Directly above the capacitors closest to the microcontroller we can see a 3.3 V low dropout regulator. We’ll take a closer look at these in a future post.ĭirectly above the jack lies a 5 V low dropout voltage regulator. To the right of the power jack are two 47 ♟ capacitors. The oval-shaped silver object in the middle left is the 16 MHz crystal. They trigger on either a LOW, a rising edge or falling edge, or a change in value via software. Two of the inputs support hardware interrupts. The Arduino Uno also supports basic communications standards like TTL serial, SPI, I2C, and 1-wire. Out of the 14-total digital I/O pins, six can be used to generate PWM (pulse width modulation) signals. The six analog pins can also serve as general purpose digital I/O. On the bottom left we have the power pins, and the analog pins dwell on the lower right (notice the small gap between them). These headers are separated into three groups.

Obviously, the rectangular thing in the lower right is the brains of the Uno, the ATmega328. Refer to figure 1, which shows the Arduino Uno. There are many shields that are available which easily attach to the board adding functionality.Īnd finally, they’re great for experimenting and prototyping projects (though my Getting Naked post explains why you may want to go for a stand-alone micro instead).

The hardware and the software are both open source, so others can take the designs and improve them without worrying about licensing fees.

Then there’s the fact that the software to program it is free and can be used on Windows, Mac, or even Linux. The boards are very versatile and can handle most common things microcontrollers can do, and the price is low. Since then, there have been various incarnations of the board including the Duemilanove (2009 in Italian), the Diecimila (which means 10,000 in Italian to celebrate the making of the 10,000 th one), the Mega 2560, and more. Made in Italy, the Arduino showed up on the scene in 2005.

Now, let’s have a closer look inside the Arduino Uno. If you’re looking for the Arduino Uno and ATmega328 pin-out, see figures 1 and 2. I may not write them in order (I may write about other topics before posting part 2), but they’ll eventually come. We’re going to take a closer look inside the Uno and see what makes it tick.Īctually, this will likely be the first of a series of posts about the inner workings of the Uno and the nuances of working with it. Though many of us have used the Arduino Uno, most of us seldom think of how it works or what’s under the hood. They both have their pros and cons, so if you’re interested check out Getting Naked: Working With Naked Microcontrollers vs Trainers Like Arduino. In fact, if you’ve been dabbling in electronics for more than a few minutes or have worked with microcontrollers, chances are you’ve used it before or have at least heard of it.Ī while ago, I wrote an article about using the Arduino vs a stand-alone microcontroller (like the ATmega328 that powers the Uno or a PIC). Of all the different incarnations, the Uno remains one of the most popular. It does not store any personal data.Since their inception in 2005, Arduino development boards have become a favorite among hobbyists, makers, and experimenters.
