Building from the concept of the singing plant, we created a tree that reacts to touch, brightening and dimming LEDs within its branches. Using a AC switch mode power supply as a switch mode generator to create noise, the plant’s capacitance is measured, and added to when a human touches it (thus adding capacitance). As the voltage varies, the noise changes and is filtered in such a way that the lights get brighter as the tree is being touched. Depending on how long the tree was touched for, the lights fade away to nearly being off until they regain a steady flow and return to a normal lit state.Currently, this is being done via Arduino, a string of Christmas LEDs, and wire connecting to the soil of the plant however, it is currently under reconstruction to reduce this from the Arduino to a single ATTiny45(See in video, a prototype test on a tomato)Created by Dzl
