Possibly the most exciting activity at the EACH Winter School 2018 is the teamwork aiming at building some simple instrumentsusing the Arduino Integrated Development Environment (https://www.arduino.cc, see also https://en.wikipedia.org/wiki/Arduino).

The instruments built were thermometer, light intensity meter and turbidimeter (!). All are small and simple, but highly useful devices. The Arduino motherboard is programmed and the obtained data are managed using laptops and a dedicated software. So, instruments can be built at very low cost and virtually everywhere.

 

It is quite a joy to generate analytical data (even if not the most accurate) using an instrument that the student has built his/herself!
