(This article designs a cylindrical LED rotating screen based on AVR chip technology and patch technology. In terms of volume, the flashing screen is more petite and exquisite, and it is particularly involved in the installation of wireless infrared remote control, so that the flashing content can be updated in real time. At the same time, the flash screen is rotated and flashed by a row of 16 SMD LEDs, so the flashed text or picture content can be viewed from a 360° omnidirectional range, which is also impossible for traditional flat screen flash screen systems.)
