Abstract: This paper develops prototype installations with an embedded system and processes measured data by writing programmes. It explores how to improve digital design teaching of landscape architecture by exploring designs of open source hardware through experiments for capturing dynamic changes to small environmental factors, installation-lamp interaction experiments, and experiments for keeping dynamic records regarding sources of water flow. In the experiments for capturing dynamic changes to small environmental factors, flow routes are selected by developed portable measurement devices and wireless data transmissions. Within the period when environmental changes are relatively stable, the section lines along the flow routes are identified for measurements of the environmental factors to lay a foundation for intensively exploring relationships between feature changes and small environmental factors in terms of data. Embedded systems and various environmental sensors are applied in the installation-lamp interaction experiments to examine responses to installations and environmental changes as well as ways of interactions between installations and people, in an attempt to find a mechanism which can better induce interactions, so as to provide necessary references for further experiments about interactive art installations. The experiments for keeping dynamic records concerning sources of water flow derive from specialized experiments of landscapes. In these experiments, existing physical models are used for capturing objects which drift with water flow, collecting data about coordinates and recording trajectories via visual tracking, in order to make it possible for digitalizing teaching experiments.
