10 Xmega Web Server Board
     The microcontroller board described here is particularly      well suited to

     monitoring and control applications. The plug-in TCP/IP module allows

     you to implement a web server and other network-oriented applications

     and a microSD card provides mass storage. Four LEDs, four buttons,

     and a removable display provide the user interface options.

     And of course the board comes with a wide range of external interfaces.
22 8x8 Two-color LED Matrix
     This article describes an alternative method for driving a matrix consisting

     of a large number of LEDs, while using only a few I/O lines from a

     microcontroller.

     As an example application for this circuit, a small game was developed in

     which an LED can be directed across the matrix using a joystick.
30 Numitron Clock & Thermometer
     The idea for this project was to take the Arduino world off of its Shields and

     Breadboards and out into a world of Elektor DIY projects while also hopefully

     Electorappealing to the diehard AVR hackers. These worlds are so close but are so

     often treated as separate. The project happily combines today's

     microcontroller technology with 1950's Soviet tubes now available 'NOS' from

     Ebay.

36 Android Elektor CardiVscope
     Here now is the last installment of the article series, concentrating on

     calibrating the pre-assembled board. The job is done using a few home built

     resistor networks, and dedicated software running on the smartphone.
DesignSpark
44 Modular RF Link using Manchester Code (2)
     Having concluded the hardware side of this project, it's time to go software.

     While the proper hardware design and board layout guarantees the correct

    Elector radiation and reception of the RF signals, the software (sometimes referred

     to as firmware) plays a fundamental role in the reliability of the message

     being carried by the signal. We're off to Manchester!

52 DesignSpark Tips & Tricks, Day #4: A Simple Project
     Having learned how to set up and use libraries in DesignSpark, we can

     proceed with the schematic and circuit board editors. Today we'll make a

     simple bi-color LED driver to get the hang of it.
Labs
56 Getting Started with the LPC800 Mini Kit
     The NXP LPC800 Mini Kit sports an LPC810 32-bit ARM Cortex-M0+

     microcontroller (MCU) in an 8-pin DIP package, a voltage regulator, two

     Elektorpushbuttons, an LED and two small prototyping areas. Here are a few hints

     to get the board up and running in no time. 

60 Negative Energy
     How on earth can three series connected 1.5-V batteries persistently

     supply ... 1.5 volts?
