[Stan] built this LED matrix using a 16×16 grid of RGB LEDs. He built the hardware and wrote some subroutines to randomize the colors. He’s not using PWM because frame buffering is not feasible for ...
A few years ago, [Frans-Willem] bought a few RGB LED panels. Ten 32×16 panels is a lot of LEDs, and to drive all of these panels requires some sufficiently powerful hardware. He tried working with an ...
At the heart of that microscopic LED is a gallium nitride semiconductor which emits either red, green or blue light depending on the applied voltage. In a recent demonstration of the technology at the ...
