so I'm almost completely new to programing
so I desided to teach my self with a peggy 25x25 led board
I studied the examples for peggy and the arduino reference and examples but for my first program I wanted to make a random Led on the board light up one at a time
OK so if I want to create a random value that changes each time the frame is displayed what do I do?
is this the most efficient way?
// random dot.
#include <Peggy2.h>
Peggy2 frame1;// Make a frame buffer object, called frame1
float r; //first random number
float r2; //second random number
void setup()
{
frame1.HardwareInit(); // Call this once to init the hardware.
// (Only needed once, even if you've got lots of frames.)
} // End void setup()
void loop() // run over and over again
{
r = random(0, 24); // value is between 0, 24 the grid size on the LED board.
r2 = random(0, 24);
frame1.SetPoint(r2, r); // radom led coordinates
frame1.RefreshAll(500); //Draw frame buffer one time
if (r = r) // if random number = itself
frame1.Clear(); //then refresh the image
}
feel free to tare me apart I really am only just beginning to understand this and I'm no good at maths :
