"Raindrop" is a pocket-type extremely portable virtual instrument hardware platform that integrates more than 12 commonly used experimental instruments. After installing “Instruments Playground” software on the computer and connnecting “Raindrop” to the computer via USB cable, the combination enables learner embrace a basic engineering test and measurement laboratory. Learners can complete hands-on experiments while learning engineering MOOC courses (from Circuits to Signal System, from Sensors to Control, etc.) to correlate between theory and practice , to improve learning outcomes.
