Simple LED matrix. Arduino does the rest. Use digitalWrite() for x and y location. Sample code gives different effect.
Void setup()
{
// set pins 2 - 9 as output
For(int x = 2; x < 10; x++)
{
pinMode(x, OUTPUT);
}
}
void main()
{
// pins 2 - 5 are x, pins 6 - 9 y
for(int x = 2; x < 6; x++)
{
for(int y = 2; y < 10; y++)
{
digitalWrite(x, HIGH);
digitalWrite(y, HIGH);
delay(125);
digitalWrite(x, LOW);
digitalWrite(y, LOW);
}
}
}
