Best Practice
LabPi was developed for teaching practice from the very beginning. Each sensor opens up new experimental possibilities for teaching and learning. The following examples show how they can be used profitably.
New: Materials and experiments for working with LabPi - the offer is constantly being expanded and will soon be translated into English
