In everyday praxis, we often need demonstration measuring devices (thermometers, pH meters, etc.), with large enough displays to be easily readable from every point in the classroom. Here, we present some of the capabilities of the Arduino platform for the school environment. This microprocessor board can be used for inexpensive construction of measuring devices for demonstrations and experiments performed by students in chemistry.

In everyday praxis we often need to demonstrate measuring devices-such as thermometers, manometers and voltmeters-with large enough displays that they can easily be read from anywhere in the classroom. In some cases, computers with a measurement interface can be used as a substitute, but often this is not possible (for example in the lab or in an outdoor environment). We present a low-cost basis for demonstration devices that can also be used in situ as data loggers or in the classroom as computer interfaces.
