Tutorial to Use Infrared Receiver Remote Control With Arduino

To do this tutorial, you will need :

1. Arduino Uno Board and USB Cable
2. IR Remote Control
3. IR Receiver
4. Jumper Wires
5. LCD 16X2
6. Resistor 10K

• Pin 1 is signal
• Pin 2 positive power
• Pin 3 is ground

1. Connect your IR Receiver to Arduino Uno Board as following :

• GND to GND
• VCC to 5V
• SIGNAL to Arduino's D11 (you could use any digital pin number)

2. Connect your LCD to Arduino Uno Board as following :

• VSS to +5VVDD to
• GNDRS to 12
• RW to GND
• E to 11
• D4 to 5
• D5 to 4
• D6 to 3
• D7 to 2
• A/VSS to +5V
• K/VDD to GND

3. Connect 10K Potentiometer to LCD as following :

• GND to GND
• Data to V0
• VCC to +5V

4. After completely connect the whole circuit, connect your Arduino Uno Boad to your computer using USB Cable.

You have to download both of these libraries. Open and extract this to your Arduino's Libraries folder. refer the picture above if you need help on how to extract the libraries.

decoder.rar is a sample source code that will help you recognizing your ir signal number and remotecontrol.rar is a sample source code that will show you how ir remotes control work. Download both of the sample source code below and this sample source code will be explain on the next step.

Unpack decoder.rar and open it on your Arduino IDE. Go to Tools > Board > Arduino/Genuino Uno and Tools > Port > select your Arduino's port. Then, upload decoder sample source code on your Arduino board. via USB cable. Wait till Arduino IDE done uploading and open the serial. Now, press any button on your IR Remote control. Your serial monitor should have print you some numbers.

------------------------------------------------------------------------

I click OK button and serial monitor print :

• 16712445
  

when I click OK button and hold it for a while. Serial monitor print

• 16712445
  4294967295
  4294967295
  4294967295
  

Now, i click number 1 button and hold it for a while. Serial monitor will print

• 16738455
  4294967295
  4294967295
  4294967295
  

You can see that when you hold up any button for a few second, you will get a repeating value (4294967295). Thus, it obviously the first number that matter. Now, repeat the same step for all button and record the first number printed when you press you remote control's button. You will need the signal number of your IR remote control it for the next step.

This is my IR Remote Control signal number :

• OK Button = 16712445
• UP Button = 16736925
• DOWN Button = 16754775
• LEFT Button = 16720605
• RIGHT Button = 16761405
• Number 0 = 16730805
• Number 1 = 16738455
• Number 2 = 16750695
• Number 3 = 16756815
• Number 4 = 16724175
• Number 5 = 16718055
• Number 6 = 16743045
• Number 7 = 16716015
• Number 8 = 16726215
• Number 9 = 16734885
• * Button = 16728765
• # Button = 16732845

Now, unpack your remotecontrol.rar and open the .ino file. Notice this code below in the remotecontrol.ino

case 0: //change zero to your IR remote UP button number
lcd.clear();   
lcd.print("UP");
break;

You have to change 0 to whatever number your IR remote button makes. Below is the example code :

case 16736925: 
lcd.clear();
lcd.print("UP"); 
break;

You have to change 0 to your remote control's OK's signal number for case that print lcd.print("OK"). Do this for all button you have on your remote control. Refer the picture above for more understanding. When you have completely updating your case number, check your board and port again, and upload the code into your Arduino Uno Board.

1. When user press number 6 on IR Remote , LCD will display 6 on LCD
2. When user press OK on IR Remote, LCD will display -OKAY- on LCD

this is applied to all button (up, down, left, right, ok, number 0-9 and etc..) based on our remotecontrole.rar sample source code.

This video shows how IR Remote control work based on our sample source code.
