and here the back image of the led matrix
81  Using Arduino / Displays / Re: problem with led matrix 8x8 with 24pin on: July 08, 2012, 02:38:17 am
the problem is my led matrix only has red color not green color and it has 24 pin that is the problem
there extra pins for row and colom

83  Using Arduino / Displays / Re: problem with led matrix 8x8 with 24pin on: July 07, 2012, 01:11:38 pm
tnx all for replay but i want which pins are colom and which pins are row and i now which pin is first pin
and i want the connection circuit like first pin on the matrix should connect to which pin on the arduino and with code
please help
tnx for rel smiley

HI
I visited this website http://arduino.cc/playground/Main/DirectDriveLEDMatrix
and it was good but the problem is my led matrix has 24 pin but the circuit in the website has 16 pin and I try a lot with it but doesn't work like some led work but the other won't ,it doesn't show the correct message like when you want to show "L" it doens't

please help
85  Using Arduino / Programming Questions / IR remote receiver and Arduino on: July 05, 2012, 03:58:02 am
I used this code in arduino  to  read the receiver
Code:

#include <avr/interrupt.h>
#include <avr/io.h>

#define TIMER_RESET  TCNT1 = 0
#define SAMPLE_SIZE  64

int IRpin = 2;
unsigned int TimerValue[SAMPLE_SIZE];
char direction[SAMPLE_SIZE];
byte change_count;
long time;

void setup() {
  Serial.begin(115200);
  Serial.println("Analyze IR Remote");
  TCCR1A = 0x00;          // COM1A1=0, COM1A0=0 => Disconnect Pin OC1 from Timer/Counter 1 -- PWM11=0,PWM10=0 => PWM Operation disabled
  // ICNC1=0 => Capture Noise Canceler disabled -- ICES1=0 => Input Capture Edge Select (not used) -- CTC1=0 => Clear Timer/Counter 1 on Compare/Match
  // CS12=0 CS11=1 CS10=1 => Set prescaler to clock/64
  TCCR1B = 0x03;          // 16MHz clock with prescaler means TCNT1 increments every 4uS
  // ICIE1=0 => Timer/Counter 1, Input Capture Interrupt Enable -- OCIE1A=0 => Output Compare A Match Interrupt Enable -- OCIE1B=0 => Output Compare B Match Interrupt Enable
  // TOIE1=0 => Timer 1 Overflow Interrupt Enable
  TIMSK1 = 0x00;          
  pinMode(IRpin, INPUT);
}

void loop()
{
  Serial.println("Waiting...");
  change_count = 0;
  while(digitalRead(IRpin) == HIGH) {}                                
  TIMER_RESET;
  TimerValue[change_count] = TCNT1;
  direction[change_count++] = '0';
  while (change_count < SAMPLE_SIZE) {
    if (direction[change_count-1] == '0') {
      while(digitalRead(IRpin) == LOW) {}
      TimerValue[change_count] = TCNT1;
      direction[change_count++] = '1';
    } else {
      while(digitalRead(IRpin) == HIGH) {}
      TimerValue[change_count] = TCNT1;
      direction[change_count++] = '0';
    }
  }
  Serial.println("Bit stream detected!");
  change_count = 0;
  time = (long) TimerValue[change_count] * 4;
  Serial.print(time);
  Serial.print("\t");
  Serial.println(direction[change_count++]);
  while (change_count < SAMPLE_SIZE) {
    time = (long) TimerValue[change_count] * 4;
    Serial.print(time);
    Serial.print("\t");
    Serial.println(direction[change_count-1]);
    Serial.print(time);
    Serial.print("\t");
    Serial.println(direction[change_count++]);    
  }
  Serial.println("Bit stream end!");
  delay(2000);
}
then i get these results
when i send command from transmitter
Code:
Waiting...
Bit stream detected!
