RGB LED Tutorial (using an Arduino) (RGBL)

Step 2 Testing

Before we connect our RGB LED to our Arduino it's a good idea to give it a test.

Consult your RGB LEDs datasheet for its pin-out or below are the two most common RGB LED form factors and pin-outs.

Wire up the Test Schematic (below)

• Plug the RGB LED into your breadboard
• Connect a current limiting resistor to each of the three cathodes
• Connect the common anode to 5V (5 volts)
• Test each color by connecting its current limiting resistor to ground (GND)
• Experiment with colour mixing a little by powering multiple elements at once
