Using this LED module is easy. First, connect it to your Arduino board following the pin definitions (1 for control, 2 for GND, and 3 for power). To turn it on, set the digital pin to LOW, and to turn it off, set it to HIGH. You can adjust the brightness by using PWM output. When handling the module, make sure the voltage is within the +3.3 - 5V range to avoid damage. Keep it in a dry and clean place. If you're not using it for a long time, disconnect it from the power source. Regularly check the connections to ensure stable performance.
