Lissajous Figures on 8X8 Led Matrix

Lissajous Figures on 8X8 Led Matrix

A point of light oscillating in 2 perpendicular axes draws a pattern namedΒ “Lissajous Figure”Β (1857) orΒ “Bowditch Curve”Β (1815). Patterns range from simple to complex depending on the frequency ratio and phase of the 2 axes.A 1:1 ratio with 0 phase difference draws a straight line at 45Β° angle. In this project the frequency ratio of the 2

Germany takes a step to imaging LED matrix headlamps

Germany takes a step to imaging LED matrix headlamps

Arbitrary-beam headlights are another step closer, claims a German consortium. Cars already exist in which cameras shape the headlight beam around other road users – maximising light on the road while minimising dazzle. These adaptive headlamps are based on forward-facing cameras and shaped mechanical shutters within the headlight. With the advent of LEDs, headlamp developers

LED Matrix Backpack schematic

LED Matrix Backpack

I had purchased some huge (2β€³) 5Γ—7 matrix a while ago, as part of my led sensor research. They’ve basically been banging around the lab since, getting pins bent and such. So this past weekend, I decided to put them to some other use. Their pin layout is sort of weird, it doesn’t match up

Making a 8Γ—40 LED matrix marquee using shift registers

LED matrix displays provide flexibility to display text, graphics, animations, and video, and therefore, they have become a popular mean of displaying information these days. You can see them at gas stations displaying the gas prices, or in the public places displaying information, and alongside highways displaying advertisements on large dot matrix panels. This project
