Discover the secret life of plants! FLORANIUM FDRM-KL25Z Shield An experimental Polygraph for green plants. www.floranion.de
Dependencies: FastPWM SPI_TFT_ILI9341 TFT_fonts
SOME BELIEVE PLANTS CAN FEEL OUR PRESENCE...
The FLORANIUM PROJECT is an innovative plant life indicator, similar to a humans polygraph, that allow you to visualize activities of living plants, caused by movement, touch, changes in climate, environment and many other elements of life. It's a whole new way to interact with green plants!
