A master computer, which can be either a Raspberry Pi or a Linux PC, is in control of the wall and plays video files. This communicates to all the Raspberry Pi ’tiles’ of the wall via an ethernet network. Each tile displays part of the picture on its screen, and the screens together form the ‘wall’.
The combination of master and tiles together forms a PiWall video wall system. The PiWall can be either fully stand-alone or the master can be connected to an external network via an additional wired or wireless network adapter, thus enabling the system to be controlled remotely.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
