Do-it-yourself LED matrix If you need a small LED matrix of a non-standard size or shape you can make one on your own by using a development board, LEDs, and current-limiting elements.So let's make a 10x10 matrix with ultraviolet LEDs. In this way we'll get a money authenticity detector.We'll use ECI development board by Velleman, 100 LEDs, and 100 resistors.You may ask why we need so many
