Introduction: Arduino Based IR Remote Decoder
To decode any universal remote values we can use this code and schematics. This is Arduino Based IR remote decoder.
Supplies
Step 1: Intro
Hello guys, today in this tutorial we are going to make an IR Hex data decoder using Arduino. We will print the values of decoded data on LCD. The schematics, circuit diagrams, PCB layout and Arduino code will be described in detail. In last we will focus on some IR remote libraries and discuss the problem in these Arduino libraries.

Step 2: Basic Idea
Every digit/button of IR remote have identity number. This is given by microcontroller inside remote control and transmitted through IR led. This data is in the form of 0 and 1. To understand the data in Hex format, we need to capture it and decode using microcontroller. We will capture this data using TSOP1738 IR receiver and decode the data using Arduino’s Atmega328p.
Step 3: Breadboard Schematics
Step 4: Components Required
1) TSOP1738
2) Arduino
3) 16x2 LCD (with I2C)
4) 100-ohm resistor
5) IR remote
6) 9v battery
Step 5: Circuit Diagram
Step 6: Circuit Making
The circuit is too simple, just put IR Tsop receiver and give power using GND and VCC lines. Connect data pin to any digital pin of microcontroller. Print the values using I2C communication on 16x2 LCD. The values are given in Hex decoded format like: F897E456 ( 8- digits).
Step 7: Working in Brief
Each remote button number has different address, this address is given by microcontroller to each button. And the data is transmitted using IR led in front of remote. This is encoded binary data in 0101 format.
This transmitted data is received using TSOP infrared sensor. The data is decoded in Hex format (E556F562) using microcontroller.
To see the decoded data, we can use serial monitor or LCD (16x2).
Step 8: Arduino Code
/* hello guys here I am using older versions on IR library so please download and install all the previous version (to be precise IRremote-2.8.0 library).

#include <IRremote.h>

}
void loop() {
if (IrReceiver.decode())
{
Serial.println(IrReceiver.decodedIRData.decodedRawData, HEX);
lcd.clear();
lcd.setCursor(0,0);
lcd.print("IR DECODED");
lcd.setCursor(0,1);
lcd.print(IrReceiver.decodedIRData.decodedRawData, HEX);
irrecv.resume(); // Receive the next value
delay(100);
}
}
Step 9: Decoded Values for My Universal Remote
This is a universal stereo Bluetooth remote and the values are same for all remotes of this type/ you can match 1-2 values and then go with this decoded data.

2) FE017F80
3) FB047F80
4) F8077F80
5) F50A7F80
6) F30C7F80
7) FF007F80

Step 11: Arduino Library and Problems
Step 12: Implementation and More
I think the solo project is not valuable, we can decode the data and make different project using these decoded values. Like:
A remote clone, which not exactly looks like a remote to a lay man.
RC car using Arduino and IR remote.
FAN, Light controller relay system.
