REMOTE CONTROLLED LEDS

    

 

WANT TO CONTROL YOUR ELECTRONIC DEVICES WITH ANY REMOTE ? WELL YOU'RE IN THE RIGHT PLACE

Here, we will create a system that controls LEDs through IR signals of a remote. This project is called "Remote Controlled LEDS".

WORKING PROCEDURE 

Active IR Sensors can emit IR radiation as well as detect it. In this project a remote transmits IR signals and an IR sensor receives it. The HEXADECIMAL code is noted down for each button pressed ,applied in the code and necessary commands are written to control the LEDs.

Keep in Mind:

• Resistor of at least 100 Ohms should be connected in series with each of the LEDs to protect it from getting damaged.
• The HEX code must be placed correctly in the code.
  
• Some remotes generate multiple HEX values of  a single button. So the buttons should be pressed within a very close range of the IR receiver. This will solve the problem for most of the cases.
  

THE COMPONENTS

• ARDUINO UNO BOARD                              
• LED:--> BLUE-YELLOW-WHITE [ according to your wish ]                
• RESISTOR 100 Ohms - X3
  
• IR SENSOR                  
  
• BUZZER
• BREAD BOARD
• ANY REMOTE                            
  
• JUMPER WIRES ( M-M | M-F )
