Started Arduino about a month ago, first of course some simple led examples but having some programming experience (basic), I was triggered for something more exciting.
Please note that English is not my native language so language errors WILL occur!
I wanted to make a led-matrix that could be easily configured by GUI (and I made it!)
first of all lets start with the matrix:
- 25 standard led's and resistors (220 Ohm)
- soldered the matrix, lots of schemes can be found on the net, the main idea is that rows and colums are created with the anode/ cathode of the led's (for example here!)
- then the software; I created the sketches in steps, started easy with showing constant variables and moving them along the matrix, then Serial input via console window and at last the processing application.
Arduino sketch:
byte matrix[]={B00100, B01010, B00100, B00000, B00000};
byte temp[]={B00000, B00000, B00000, B00000, B00000};
const int led_row[] = {2, 3, 4, 5, 6};
const int led_col[] = {11, 10, 9, 8, 7};
const int led_array = 5;
const int duration = 2000; //2sec
byte row0Byte;
byte row1Byte;
byte row2Byte;
byte row3Byte;
byte row4Byte;
void setup(){
Serial.begin(9600);
for (int i = 0; i < led_array; i++){
pinMode(led_row[i], OUTPUT);
digitalWrite(led_row[i], HIGH);
pinMode(led_col[i], OUTPUT);
digitalWrite(led_col[i], LOW);
}
}
void loop(){
if (Serial.available() > 0) {
matrix[0] = Serial.read();
matrix[1] = Serial.read();
matrix[2] = Serial.read();
matrix[3] = Serial.read();
matrix[4] = Serial.read();
}
wnd_showmatrix(matrix);
}
void wnd_showmatrix(byte * matrix){
unsigned long start = millis(); // begin timing the animation
while (start + duration > millis()){ // loop until the duration period has passed
for (int i = 0; i < led_array; i++){
digitalWrite(led_row[i], LOW);
for (int j = 0; j < led_array; j++){
boolean pixel = bitRead(matrix[i],j);
if (pixel == 1){
digitalWrite(led_col[j], HIGH);
delayMicroseconds(400);
digitalWrite(led_col[j], LOW);
}
}
digitalWrite(led_row[i], HIGH);
}
}
}
