Description
RGB LED MODULE In Pakistan ,RGB LED MODULE FOR ARDUINO, PC AND RASPBERRY PI.
This 1 watt RGB LED module can emit various colors of light. … The three primary colors, red, green, and blue, can be mixed and compose all kinds of colors by brightness, so you can make an RGB LED emit colorful light by controlling the circuit.
KEY FEATURES OF LED RGB MODULE:
- RGB (Red/Green/Blue SMD LED
The LED is a common cathode type which means all 3 of the LEDs have their cathodes tied together. The cathode connects to ground and the red, green and blue LED pins should connected to digital or PWM output pins with series resistors to limit current to 30mA or less.
Recommended resistor values are around 120 ohms for green and blue and 180 ohms for red. If the uC you are using is limited to 20mA on the output pins, you can increase these values to around 180 ohms and 270 ohms respectively. Higher values could use but will reduce the brightness.
