The project is an arduino with some LEDs and a Sound Sensor that blinks in different modes. Such as: Blinking when a sound is detected, randomly or with an spinning effect. The modes can be controlled by a potentiometer to increase or decrease its speed. The eletronic part is quite simple, basically an arduino, leds, resistors, a sound sensor, a potentiometer and a push button, but the cool part is the shape of the circuit boards and the overall appearance of the project.
Kinetic Sculptures: The Interactive Flower
The Interactive Flower is the intersection of nature, origami, and microcontrollers. It teaches you how to map environmental analog inputs into smooth, gorgeous mechanical outputs (like a blooming flower) and glowing gradients.
Mechanical Origami
- The Stem: A Capacitive Touch Sensor or a Flex Sensor is hidden in the stem. As a person approaches and touches the stem, the analog values change.
- The Bloom: The Arduino maps that touch value directly to an SG90 Micro Servo hidden in the base of the flower.
- The Petals: Using a clever arrangement of taut strings (like tendons) connected to the servo horn, the 3D printed or paper petals slowly, mechanically unfurl as the servo winds the string.
The Glowing Stigma
At the exact center of the blooming petals is a cluster of WS2812B NeoPixel LEDs.
- While closed, the LEDs are off or pulse a deep, dim red (like a heartbeat).
- As the servo blooms the flower open, a
forloop dynamically changes the NeoPixel colors: transitioning from Red -> Orange -> Yellow -> Blinding White. - The
FastLEDlibrary makes creating the color gradient incredibly easy.
Hardware Needed
- Arduino Nano or Trinket: To hide inside the small vase/base.
- SG90 Micro Servo Motor: Powerful enough to pull paper tendons.
- NeoPixel Ring or Strip (5V).
- TTP223 Touch Sensor (can be soldered to a long copper wire wrapped around the stem).
- Fishing Line and Fabric/Paper.
This project proves that Arduino is just as much for artists and designers as it is for roboticists.
