The Getting Started with Arduino kit V2.0 from the Maker Shed includes everything you need to join the tens of thousands of engineers, designers, artists and hobbyists who have discovered this incredible and educational prototyping platform. We include an Arduino UNO, the incredibly popular Getting Started with Arduino Book by Massimo Bansi, and all the components needed to go through the examples in the book.

[Martin Nawrath] from Lab3, Cologne, made a nice ADC tutorial based on the 18bit LTC2400:
If the resolution of the Arduino is not enough for your application you have to try it with a better ADC. The LTC2400 gives you a resolution of up to 24 bit at a datarate of 5 samples per seconds and is quite simple to connect. With this device you can connect sensors which have only a low output level like thermo couples or force strain gauges. The high sensitivity can make the use of of an preamp needless.
Since the LTC2400 comes in an SO8 package the circuit was breadboarded on a SMD prototype board which is available at your electronic shop.
The to communicate with the LTC2400 the Software makes use of the ATMEGA168 hardware SPI. To print a float type number the “printFloat” procedure found in the Arduino Playground was used.
