For all participants of the LED matrix animation workshop during the “Exploring Digital Practice in Creative Learning and Participatory Arts” conference at the Lighthouse in Glasgow – here is a few instructions here:
Instructions for LED Matrix workshop

and the sample code for the LED matrix to copy:

// https://xantorohara.github.io/led-matrix-editor/

#include <LedControl.h>
const int DIN_PIN = 7;
const int CS_PIN = 6;
const int CLK_PIN = 5;

////////////////////////////////////////////////////////
// insert the code from the matrix editor website below
////////////////////////////////////////////////////////
LedControl display = LedControl(DIN_PIN, CLK_PIN, CS_PIN);

void setup() {
display.clearDisplay(0);
display.shutdown(0, false);
display.setIntensity(0, 10);
}

void displayImage(uint64_t image) {
for (int i = 0; i < 8; i++) {
byte row = (image >> i * 8) & 0xFF;
for (int j = 0; j < 8; j++) {
display.setLed(0, i, j, bitRead(row, j));
}
}
}

int i = 0;

void loop() {
displayImage(IMAGES[i]);
if (++i >= IMAGES_LEN ) {
i = 0;
}
delay(100);
}
