This art display system was created by [Peter Sand]. It is called Plant Fasting and is comprised of a giant robot with interchangeable tools for various gardening tasks. Though the system is mostly automated, it can be controlled via a game pad. It has an Arduino as its brain and it looks like he’s done a completely custom setup for powering the interchangeable pieces.
We’ve covered automated plant growing before, but that project might be overkill for many situations. Many of us don’t need our plants to have facial expressions either. Sometimes, we just need a little bit of help. This automated grow light is a nice little project that supplies decent light when necessary. You can download the source files on the tutorial. It is currently set to supply an additional 4 hours of light, detecting the low light levels to turn it on.
