Circuit Skills: LED Matrix

Learn How to Build a LED Matrix

By Collin Cunningham

Many an experimenter, hacker, tinkerer and maker have heeded the call of the mighty matrix – and it's no mystery why. A small army of LEDs elegantly wired in grid formation would be difficult for anyone with an appreciation for electronics hardware to pass up - even after considering the sometimes daunting wiring job that stands as prerequisite to entry.
