Loop through available characters & symbols to see what they look like on a Matrix display.
LED Matrix breadboard - Arduino Uno
Fritzing diagram: docs/breadboard/led-matrix.fzz
Run this example from the command line with:
node eg/led-enumeratechars.js
var five = require("johnny-five");
var board = new five.Board();
board.on("ready", function() {
var matrix = new five.Led.Matrix({
pins: {
data: 2,
clock: 3,
cs: 4
}
});
matrix.on();
var shapes = Object.keys(five.Led.Matrix.CHARS);
var enumerate = function() {
var i = 0;
board.loop(500, function() {
if (i < shapes.length) {
matrix.draw(five.Led.Matrix.CHARS[shapes[i]]);
i++;
}
});
};
enumerate();
this.repl.inject({
matrix: matrix,
enumerate: enumerate
});
});
