An oasis in the desert is the quintessential image of salvation for the wearied wayfarer. At Burning Man 2016, Grove — ten biofeedback tree sculptures — provided a similar, interactive respite from the festival. Each tree has over two thousand LEDs, dozens of feet of steel tube, two Teensy boards used by the custom breath sensors to create festival magic.
Grove works like this: at your approach — detected by dual IR sensors — a mechanical flower blooms, meant to prompt investigation. As you lean close, the breath sensors in the daffodil-like flower detect whether you’re inhaling or exhaling, translating the input into a dazzling pulse of LED light that snakes its way down the tree’s trunk and up to the bright, 3W LEDs on the tips of the branches.
Debugging and last minute soldering in the desert fixed a few issues, before setup — no project is without its hiccups. The entire grove was powered by solar-charged, deep-cycle batteries meant to least from sunset to sunrise — or close enough if somebody forgot to hook the batteries up to charge.

The ‘Internet of Flowers’ is upon us thanks to an artist named [Adrian]. He has designed a project that not only monitors the growth of Poppy Flowers but also monitors the soil, air and surrounding activity.
The entire project is based on a Raspberry Pi mounted in a purpose-built enclosure made from laser cut birch plywood. The enclosure is mounted in a window of an adjacent building that has a view of the flower bed. An internally mounted camera was carefully aligned so its field of view was mostly of the plants and would limit taking photos of unknowing passersby. The camera takes a snap shot every 5 minutes, see the time lapse video below.
A box containing sensors is installed in the flower bed. The intent of this project was not to have the Raspberry Pi spit out hard factual data regarding soil moistness, temperature and ambient noise, but to instead take that data from the sensors and send out a story-like narrative that makes the communication feel more personal. To receive these comments from the poppies, you can follow them on Twitter: @tweetingpoppy.

To the casual observer this flower looks nice as its illuminated center fades in and out. But there’s hidden meaning to that light. Some of the blinks are longer than others; this flower is using Morse Code.
[Renaud Schleck] wanted to try a few different things with his MSP430 microcontroller. He decided on an LED that looks like a flower as it will be a nice piece of decor to set around the home. To add the Morse Code message he wanted something a bit more eloquent (and less distracting) than purely digital flashing. So he took the dots and dashes of the hard-coded message and turned them into fading signals by using Pulse-Width Modulation.
He free-formed the circuit so that it, and the coin cell that powers it, would fit in the flower pot. A reed switch is responsible for turning the juice on and off. When placed near a magnet the flower begins its gentle playback.

This pleasant-looking plant may try to take your hand off if you’re not careful. The robot flower (translated) includes sensors that cause the petals to move in reaction to external stimuli.
You can just make out the distance sensors as black rectangles on two of the petals. These let the flower track an object by rotating the flower stem. But if they determine the object is getting a bit too close for comfort, the servo motor on the back of each petal will cause the flower to suddenly clamp shut.
The video after the break starts off with an in-depth look at the hardware that went into the project. An Arduino clone called the GRoboduino makes this project a lot easier since it has a bunch of extras on the board aimed at things like sensors and servo motors. The mounting technique for the petal-powering-servos is quite attractive, and we enjoy the Snapple lid (probably not the actual brand but you get the picture) which has been coated with yellow felt for the center of the bloom. The final look is normal enough to fit in with home decor, but it still has enough geek in it to melt our hacker hearts.

[Johannes Agricola] recently held a workshop at the Peace Mission in Goettingen, Germany where he shared his RGB LED flowers. The small round PCB hosts an ATmega88 microcontroller which is running the V-USB stack so that the unit can be controlled by a computer. Each flower blossom is an RGB LED connected with four enameled wires which, when twisted together, make up the stem of the flower. [Johannes] took tons of pictures during the assembly while offering soldering advice along side the illustrations. The PCB is single-sided helping make this a great project for someone trying out surface mount component soldering for the first time. Or if you want something a little more free-formed try out this lemon-juice powered LED flower.
[Madaeon] pointed us toward this entry for the Instructables Epilog challenge. While this may not be extremely complex, or have as many wires as our typical post, it is a fantastic example of thinking outside the box. How many lemon batteries have we seen? A lot. This one stands out as being more elegantly displayed and functional at the same time. In its final form, you sprinkle lemon juice on it’s petals and it lights up. If you ever find yourself in the position of teaching someone about electronics, remember this project. Sometimes aesthetics can make a dull simple project take on a life of its own.
