The Arduino Yún is the latest board from Arduino and it's a doozy! It combines the ATmega32U4 (as used in the Arduino Leonardo) with the Atheros AR9331 System on a Chip (SoC). The Atheros runs a Linux distribution, Lininio, and is connected to the USB host, microSD card slot and the WiFi chip.
The power of the Yún comes from the combination of these two. Linked by a software Library called Bridge, Linux handles all of the difficult parts of the WiFi and Ethernet stack, managing USB host and dealing with the mass storage. The Arduino side behaves as you would normally expect, controlling all of the boards I/O pins and programmed through the Arduino IDE. The magic happens when they work in concert. The Arduino side passes data to and from the Linux side, controlling and measuring real world things, whilst the Linux side can easily perform wider interactions over the internet and through the Temboo API.
With this power you can very easily create powerful Internet of Things devices with an exceptional capacity for remote control, monitoring and interactivity.
Robots can be great fun for learning about programming, especially for children, but sometimes it can be quite a bit of trouble for a beginner to build an entire robot! But do not fear, Arduino is here. They made a fully featured and assembled robot that you can start learning on right away.
It features two ATmega32U4 boards, one to control the motors, the other to manage sensor inputs, which include a compass and line following sensors. The robot is powered by four rechargeable AA batteries through a mains adapter and features a 1.7" LCD display and keypad on the top of the Robot!
Say hello to the Trinket! This is a really tiny board (smaller than two 5p pieces!) powered by the equally tiny ATtiny85. But don't let any of that fool you into judging it purely by its size, it's got a USB micro slot for power and programming; 5 GPIO pins - 1 analog in, 2 PWM and hardware I2C and SPI; 8K of flash and it's available in 3.3V and 5V versions!
It doesn't stop there! Loads of Arduino libraries produced by Adafruit will already work with the trinket allowing you to control LED and LCD displays, servos and emulate USB 1.1 devices. Topping this off is the fact that it only costs about as much as a pack of cigarettes!
You've probably already met E-paper on e-readers like the Kindle, well now you can start putting it in your own projects! E-paper, unlike ordinary displays needs absolutely no power to display an image, it only uses power when it changes the image on the screen, this gives it exceptional battery life in situations where the display's refresh rate is very low.
This 2.7" E-paper display gives you the low power, high resolution and high detail of e-paper displays in a form that's easy to work with, there's even example code for partial screen updates! No thin and fiddly ribbon cables here, just header pins that you can easily connect to anything with SPI capability. This display has a high resolution of 264x176 and mounting holes for easy prototyping and integration into projects.
