RGB LED Random Color With 433MHz RF Remote and Arduino

In this simple tutorial we will learn how to control the RGB LED Random color with a 433MHz RF Remote control and Arduino and how to turn it ON & OFF.

Watch the Video!

• Arduino UNO (or any other Arduino)
• Jumper wires
• RGB LED Module
• 433 MHz RF module
• Visuino program: Download Visuino

• Connect Remote pin [VCC] to Arduino pin [5V]
• Connect Remote pin [GND] to Arduino pin [GND]
• Connect Remote pin [D0] to Arduino digital pin [4]
• Connect Remote pin [D1] to Arduino digital pin [5]
• Connect RGB LED pin [+] to Arduino pin [5V]
• Connect RGB LED pin [R] to Arduino digital pin [6]
• Connect RGB LED pin [G] to Arduino digital pin [10]
• Connect RGB LED pin [B] to Arduino digital pin [9]

Note: some RGB LED modules have pin (-) instead of pin (+) in that case you connect it to the Arduino pin [GND]

The Visuino: https://www.visuino.eu also needs to be installed. Download Free version or register for a Free Trial.

Start Visuino as shown in the first picture Click on the "Tools" button on the Arduino component (Picture 1) in Visuino When the dialog appears, select "Arduino UNO" as shown on Picture 2

• Add "Random Color" component
• Add "Color Value" component
• Add "Color Multi-Source Merger" component
• Add "RGB LED" component
  
  
• Connect Arduino digital Out pin[4] to "ColorValue1" pin [Clock] , this will be used to turn the LED Off
• Connect Arduino digital Out pin[5] to "RandomColor1" pin [Clock] , this will be used to set the random color on the LED
• Connect "RandomColor1" pin [Out] to "ColorMultiMerger1" pin [0]
• Connect "ColorValue1" pin [Out] to "ColorMultiMerger1" pin [1]
• Connect "ColorMultiMerger1" pin [Out] to "LED1" pin [In]
• Connect "LED1" pin[Red] to Arduino Digital-Analog PWM pin[6]
• Connect "LED1" pin[Green] to Arduino Digital-Analog PWM pin[10]
• Connect "LED1" pin[Blue] to Arduino Digital-Analog PWM pin[9]

Note: If the LED is not shining then Select "LED1" and in the properties window set "Inverted" to True

In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.

If you power the Arduino module, and press the button "A" on the Remote the LED will Turn ON and a random color will shine, If you press the button "B" on the Remote the LED will turn off.

Congratulations! You have completed your project with Visuino. Also attached is the Visuino project, that I created for this Tutorial, you can download it and open it in Visuino: https://www.visuino.eu
