This is one of my 1st Arduino projects. Along with Arduino, I've used a seven segmeent led display and a piezzo buzzer. First, it beeps to indicate start. Then, counts down from 9 to 0, beeps three times. Finally, it beeps for the last time but this time the beep lasts longer.

Arduino is the go to board for most folks looking for an introduction to microcontrollers. That's largely thanks to its sizable community, ease of use and surprising versatility. But, there is one small stumbling block for those just looking to dip their toes in the ATmega-powered waters: you'll need to provide your own sensors, components and breadboard. (At least you will unless you're satisfied just making the built-in LED blink.) The Esplora bakes some of those essential bits and pieces right on to the board. It's crafted around the same core as the Leonardo, but adds an accelerometer, microphone, analog joystick, four buttons, a light sensor, temperature sensor, linear potentiometer and a buzzer to the mix. While the gamepad-like layout means you wont be able to connect to any of the dozens of Arduino shields out there, it does have a pair of TinkerKit inputs and outputs for expanding the Esplora's capabilities. There's also a place to connect an upcoming LCD module. The Esplora is available now direct from Arduino for €41.90.

The original Netduino Plus was a welcome alternative for Arduino developers that had its limits -- even networking was almost a step too far. Secret Labs doesn't want any of us to bump our heads on the ceiling with its just-launched Netduino Plus 2. The networkable, .NET-friendly developer board runs a four times faster 168MHz processor with double the RAM (over 100KB) and six times as much code space (384KB) as its two-year-old ancestor. Having so much headroom lets the team build common OneWire and Time Server code into the firmware; Secret Labs reckons that there's enough space that the Plus 2 can easily grow over time. The ports are just as ready for the future with four serial ports, software control of any add-on shields (including Rev C Arduino shields) and a new header that lets programmers debug both managed and truly native code at once. If the upgrade is sufficiently tempting, project builders just need to spend $60 today to enjoy some newfound freedom.

With the Arduino Leonardo, everyone's favorite hackable microcontroller turned a new page. Now it's time to bring that simplified design and slightly expanded feature set to the rest of the family, including the itty-bitty Arduino Micro. The tiny, embed-friendly board was designed with help from Adafruit Industries, one of the biggest players in the DIY market. At the heart of the Micro is the same 16MHz ATmega32u4 chip that powers the Leonardo, which means all the necessary USB controls are baked into the processor. Obviously, the layout here is different, so you wont be mounting the Micro to any shields, but with 20 digital I/O pins, 12 analog input channels and seven PWM channels, there's plenty of room for wiring up your own expansions. Amazingly it crams all that capability in a package just 48mm long and 18mm wide. The Arduino Micro will be available exclusively through Radio Shack and Adafruit first before becoming more widely available next month. The board is available with headers for €21 (roughly $23) and without headers for €18 (about $27). For more, check out the PR after the break.

How was your week? We got to spend a couple of days trekking around the Carnegie Mellon campus in Pittsburgh, PA to check out some of the latest projects from the school's world renowned Robotics Institute -- a trip that culminated with the bi-annual induction ceremony from the CMU-sponsored Robot Hall of Fame. Given all the craziness of the past seven days, you might have missed some of the awesomeness, but fear not, we've got it all for you here in one handy place -- plus a couple of videos from the trip that we haven't shown you yet. Join us after the break to catch up.

It's an Arduino -- you know, for kids. Or, as BirdBrain Technologies' chief robot design Tom Lauwers put it, a "pre-Arduino." It's never too early to get kids into robot building -- or so goes the thought process behind this nectar-loving kit. At its center is a custom controller that can be used to manipulate a slew of different sensors, motors and lights, a number of which are included in the box. Getting started is extremely simple -- don't believe us? Check the video after the break, in which Lauwers connects two wires to get the whole process underway.

The kit's also reasonably priced at $199 a piece. On top of the controller, you get a handful of LEDs, two vibration motors, four servos and light, temperature, distance and sound sensors. The kits are currently available through the company's site (click on that source link). Lauwers tells us that his company (which you may remember from last year's MakerFaire NYC) is working on a slightly more affordable option priced at around $130, which scales back a bit on the in-box components.

Check out a conversation with Lauwers -- and a pretty awesome cardboard dragon -- below.

CSI: Miami might be out of production, but that doesn't mean we'll be deprived of casual eyewear flipping. Not if Ben Heck has a say in the matter, at least. His latest DIY project automatically swings a pair of clip-on sunglasses into view whenever it's too sunny outside: a photocell attached to an AT Tiny microcontroller checks the light levels and, through an Arduino-based AVR MKII language, tells a rotor to spin the glasses into place. No one will be labeled a fashionista with the requisite battery pack strapped to their heads, but the construction doesn't require CNC milling and won't destroy a favorite frame. We're only disappointed that the sunglasses won't play The Who on command... yet.
