Product Introduction
This product is a 3mm diameter common cathode red green dual color LED module. According to the functional diagram, connecting the positive and negative poles of the power supply to the pins of the module can emit corresponding bright light (the positive pole connected to the R pin emits red light; the positive pole connected to the G pin emits green light).
Users can control the module by writing programs to control the microcontroller, such as controlling the on/off interval of lights, which color of light is on, and combining the time interval and light color according to a regular pattern to create different lighting effects.
