Yes, it does; if my memory serves me correctly, you'll need to use some different libraries than you would normally use with an Arduino. I'm not sure how many devices it can handle because I've only tried it with one i2c device.
It is equipped with a boot loader. All you need is a programmer to get started. The Arduino Uno and most of the variants can be used. I used an arduino micro for this project. A dedicated programmer is also an option. There are many tutorials available on how to program an Arduino. Shaun McDonough is a professional basketball player.
It depends on your definition of program, but you'll need an ISP (in system programmer).

For a simple project, you may only require a few LEDs or a simple "smart" switch, rather than an entire Arduino. You don't like the idea of sacrificing an entire Nano or Mini, or even their small footprint is too much for you. This is for you if you don't want to use a few crystals and a bunch of resistors and capacitors to power a hand-built Arduino. br>br> Connect it to your computer with only three wires*, and you're ready to go. These babies can provide you with up to 5 digital I/O ports, or a combination of digital I/O, up to 2 PWM, and up to 3 analog in! They're absolutely incredible. They can't hold large programs, but most limited I/O sketches aren't that difficult. They are also reasonably priced. The price is extremely low. A full- On the Arduino Uno (from Arduino), the price is around $35. One of these will set you back less than three dollars. With a stick, you can't beat that. As a result, don't even think about it. (Seriously, don't smack them in the face with a stick. ) There's no point in it. They're solid state, so they won't understand what I'm saying. ) If you buy them in bulk, you can get them for less than a dollar each with free shipping from Atmel or one of their distributors. br>br>These tiny guys consume power, perform sophisticated processing (albeit in small chunks), and fit on a breadboard; plus, they're a hundred times more brutal than Lego on the floor at deterring cat burglars and sleep walkers. If you step on the upturned pins of a few of these, you'll be wishing you'd chosen a different house. You have no idea how much you adore them yet, but you will. Purchase them today and incorporate them into your project or on your floor! br>br>* Programming requires far more than three wires, but once completed, they can be disconnected.
This device is exactly what I'd expect from an Atmel product. It has the promised 20MHz clock speed. br>I discovered that at mid-range clock speeds, it only cost me about 500 micro amps. If you have an Arduino that can act as an ISP, it's fairly simple to program. br>br>A must-have for hobbyists, this is a fantastic little device. At this price, you can't go wrong with stocking up on these. Because the pins are spaced evenly, making a programmer board for them is straightforward. br>br>With this product, I received quick shipping and the items arrived exactly as advertised. br>They came in a standard anti-static bag. bag with no movement.
br>I was very concerned about the internals being destroyed. br>Worked out great for my standalone laser tripwire project!br>br>However, I'm thinking about purchasing an ATmega328p. Next time, use more I/O pins because those weren't enough for slightly larger projects. Only 5 I/Os, vcc, grd, and a reset pin are available. (If I use the reset pin as an I/O, I won't be able to re-enter the code. ) I believe you can program it easily with an Arduino)br>Shift registers will suffice, but they complicate things. br>I'm hoping Atmel will sell them as well!.
These are my favorite kinds of items. They're incredible, but Atmel is my personal favorite. Your shipping needs to be improved. The pins on both of my ICs were severely bent, and they were nearly broken off several times. I had to be extremely cautious when installing them in my project to ensure that they didn't fall off.
I bought two of them for my gamecube RGB mod, and they worked perfectly. The only annoyance was the ease of use of the associated software, as well as the requirement to order a compatible USB adapter in order to load the code. I wish the loading process was more streamlined or had a better user interface. Despite this, with sufficient effort, I was able to get everything to work. These are highly recommended for any small controller. job done, and it's a pretty basic one at that.
All six of the ones I bought were of excellent quality and worked perfectly. br>In this video, three of them run the "Blink" example (100 ms) at 1 Mhz (internal), 8 Mhz (internal), and 16 Mhz (external, with crystal and 2 pF ceramic disc capacitors) at 1 Mhz (internal), 8 Mhz (internal), and 16 Mhz (external, with crystal and 2 pF ceramic disc capacitors). br>However, I did not test their ability to reach those who used an internal High Frequency PLL Clock. br>When I need more, I'll definitely go back to this vendor.
Great chips for a fraction of the price of an entire Arduino board, and they didn't have any bent pins. I used it to make a RBG led lamp that cycles through the different colors! I just wish there was one more pwm pin on this chip instead of the three analog input pins (which can be converted to normal I/O digital pins without pwm).
It gets the job done.
