Colorful Interactive Wall

Children's Playground

★Exhibit Content: RGB three-primary color mixing and pixel dot matrix imaging ★Interaction: Electromechanical interaction ★Operation: Rotate the circular light modules to adjust light color and on/off; freely combine different color blocks to create various creative patterns; when there is no operation for 30 seconds, the exhibit automatically switches to a demonstration animation. ★Exhibit Description: The exhibit consists of an outer frame box, a 464-knob light module LED dot matrix array, drive circuits, and a control system. It is a recommended exhibit from the PopsciCat Exhibit Store. The exhibit array is divided into 16 rows and 29 columns. Each knob can be rotated independently. Visitors can rotate the knobs to change the color of the corresponding LED, freely combine color blocks to draw patterns. The exhibit is equipped with a one-key reset function. When left unattended for a long time, the exhibit automatically enters demonstration mode, looping through preset patterns, allowing intuitive experience of color synthesis and pixel imaging knowledge through hands-on creation. ★Scientific Principle: An image is composed of a large number of pixel units. A pixel is the smallest indivisible basic unit of an image, and each pixel has independent color information. This exhibit relies on the RGB three-primary color light mixing principle, adjusting the brightness of the red, green, and blue chips inside the LED to mix and produce rich colors. Many independent light points combined together can assemble a complete picture, intuitively demonstrating the underlying principle of pixel imaging in screens and displays.
