Everlasting flower for your everlasting love. A perfect not-only Valentine's day gift to your loved one. This mechanical tulip will bloom into any color possible with just gentle touch of your hand. Its six petals will slowly open and light up. When petals are closed they create incredible ambient light with leaf patterns.

Tulip consists of 6 petals each with 5 SMD white LEDs. Each petal is connected with one of the Arduino output pins. Blossom hides 7 NeoPixel RGB LEDs. From an electrical point of view, the whole flower is ground and veins in petals are a positive voltage. Petals are opened by a pushrod which is going all the way down the stem to the base. The pushrod is controlled by a movement of a small hobby servo. Small leaf on the side of the stem is connected to TTP223 touch sensor inside the base and creates a capacitive touchpad. The wooden base contains a servo motor, touch IC and Arduino Nano.

Hi Jiri!!! Amazing project, very sutil and delicate. I was wanting to see the instructables profile but apparently is no supported anymore. Is there any way to understand how you made such a beautiful thing? Thanks!!!

I am planning to exchange the Arduino NANO with a wirelless controller to be able to do so :D
