How do I use remote control for my Uno R3?
What do I need for that?
Hi @ardurino1. Please provide a detailed description of what you mean by "remote control" in a reply here on this forum topic.
Are you referring to a "remote control" device such as what we use with a television? Something like this?:
If so, do you already have a remote control unit you wish to use? If yes, then please provide the details of the exact model of the remote control you have.
Bluetooth, WiFi, LoRa, RF, IR... explained here...
Can you tell me what color the pen or pencil is in my hand? I doubt it, more information is needed.
Here is a definition from Wikipedia: A remote control, also known colloquially as a remote or clicker, is an electronic device used to operate another device from a distance, usually wireless. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other digital home media appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. Note they are not all the same.
Yellow.
Sorry I tried fool you but you are close, it is a yellow feather.
What is your idea?
Something like -----
You have connected 3 LEDs (LED2, LED3, LED4) with UNO at DPin-2,3,4 respectfully.
You want to press button marked '2' on the Remote Control (RC); the signal transmitted by RC will be received by UNO, and then UNO will blink LED2 for three times at 1-sec interval?
Similarly, for button marked '3', '4'........
Yes
How far have you got so far?
Successful with other Uno projects?
Already have any RC devices?
IOW telling us more about your skill level and requirements will get more helpful responses.
1. IR Receiver (2)
2. Remote Control

3. Connect the signal wire of IR Receiver with DPin-9 of UNOR3.
4. Connect your three LEDs with DPin-2,3,5 of UNOR3 using 2.2k urrent limiting resistors.
5. Upload the following sketch.
#include <IRremote.h>
IRrecv irReceiver(9); // Create an IR receiver object on pin 11
decode_results results;
void setup()
{
Serial.begin(9600);
irReceiver.enableIRIn(); // Start the IR receiver
}
void loop()
{
if (irReceiver.decode(&results))
{ // Check if there's an IR signal
Serial.println(results.value); // Print the value of the received signal
irReceiver.resume(); // Prepare to receive the next signal
}
}
6. Press 2, 3, 4 on the RC and record what have appeared on Serial Monitor.
Thank you all for tips.
Please note here no one charges you for each character you type; you need to try to explain what you're asking and who/what you're answering. Otherwise, the best response to your post is "Yes... WHAT?" 
It's just a friendly tip for the future, so you can get more accurate, quick and helpful answers the next time...

Hi, @ardurino1
You need to reply more than;
What do you mean by remote control?
Please explain your project, what does it do, what does it entail?
