Its just a IR Decoder that can decode the HEXADECIMAL IR signals from the TV remote for further use. like programming any TV remote etc.

Its made with Freeduino (not Arduino). Freeduino is a arduino compatible low cost micro controller. You can program using Arduino IDE (just like coding for Arduino UNO). Its based ob Atmega 328 chip.

Step 1: Items Used:

1. Freeduino Board (Any arduino board can do the work as well)

2. 16/2 LCD (Blue)

3. Jumper Cables

4. Female Header Pins.

5. IR Remote (For Testing)

6. Soldering Machine

7. An old CD/DVD to mount on.

Step 2: Connecting Headers to LCD

Solder your female header in the uper side on the LCD panel so that mounting on a CD will be easier.

Step 3: Connecting the LCD to Arduino

First of all..

Shot the following Terminals:

Vcc with Led +

Gnd with Led -

Vcc with R/W

42 ohm resister between Vee and DB4

(I have used the resistor instead of connecting a potentiometer. That will help in reducing the cable connection and reduce the cost but the LCD will bw glowing at full brightness..!!)

Connecting the Jumper Cables:

Arduino > LCD

5v > Vcc

Gnd > Gnd,R/W

Pin 7 > RS

Pin 6 > EN

Pin 5 > DB4

Pin 4 > DB5

Pin 3 > DB6

Pin 2 > DB7

Step 4: Connecting an IR Receiver

Connect the IR:

Vss to Pin 13

Gnd to Cnd (Arduino)

OUT to Pin 11

Step 5: Coding:

#include<LiquidCrystal.h>
#include<IRremote.h>
LiquidCrystal lcd(7,6, 5, 4, 3, 2);
int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup()
{
  Serial.begin(9600);
  pinMode(13,OUTPUT);
  digitalWrite(13,1);
  lcd.begin(16, 2);
  irrecv.enableIRIn(); // Start the receiver
}
// Dumps out the decode_results structure.
// Call this after IRrecv::decode()
// void * to work around compiler issue
//void dump(void *v) {
//  decode_results *results = (decode_results *)v
void dump(decode_results *results) {
  lcd.setCursor(0, 0);
  int count = results->rawlen;
  if (results->decode_type == UNKNOWN) {
    Serial.print("Unknown encoding: ");
    lcd.print("Unknown encoding: ");
  } 
  else if (results->decode_type == NEC) {
    Serial.print("Decoded NEC: ");
    lcd.print("Decoded NEC: ");
  } 
  else if (results->decode_type == SONY) {
    Serial.print("Decoded SONY: ");
    lcd.print("Decoded SONY: ");
  } 
  else if (results->decode_type == RC5) {
    Serial.print("Decoded RC5: ");
    lcd.print("Decoded RC5: ");
  } 
  else if (results->decode_type == RC6) {
    Serial.print("Decoded RC6: ");
    lcd.print("Decoded RC6: ");
  }
  else if (results->decode_type == PANASONIC) {	
    Serial.print("Decoded PANASONIC - Address: ");
    Serial.print(results->panasonicAddress,HEX);
    Serial.print(" Value: ");
  }
  else if (results->decode_type == LG) {
     Serial.print("Decoded LG: ");
     lcd.print("Decoded LG: ");
  }
  else if (results->decode_type == JVC) {
     Serial.print("Decoded JVC: ");
     lcd.print("Decoded JVC: ");
  }
  lcd.setCursor(0, 1);
  Serial.print(results->value, HEX);
  lcd.print(results->value, HEX);
  Serial.print(" (");
  Serial.print(results->bits, DEC);
  Serial.println(" bits)");
  Serial.print("Raw (");
  Serial.print(count, DEC);
  Serial.print("): ");
  for (int i = 0; i < count; i++) {
    if ((i % 2) == 1) {
      Serial.print(results->rawbuf[i]*USECPERTICK, DEC);
    } 
    else {
      Serial.print(-(int)results->rawbuf[i]*USECPERTICK, DEC);
    }
    Serial.print(" ");
  }
  Serial.println("");
}
void loop() {
  if (irrecv.decode(&results)) {
    Serial.println(results.value, HEX);
    dump(&results);
    irrecv.resume(); // Receive the next value
  }
}

For this code to run you will be needing a IR Remote Library.

Jusr Goole it or you can download from here too.
