iEasyLab allows you to design digital circuits by virtual means. You select symbols from a library, such as logic components, indicators, and measuring instruments, place them on the iPad and start the simulation. The program then presents the results. In conjunction with the mobile learning tool Tec2Screen® from Festo Didactic, learning and understanding will be better and faster in the future. It's the connects that make it possible: these core elements of connected learning are a seamless link between the virtual world and the real world – unique in the world of basic and further industrial training!
