Note: There also is a Intensity Sensor (HW-477 V0.2 Hall Effect Sensor) Sensor with the same number. It is different and fulfills a different purpose. There will be a details here on how to differentiate them.
WARNING: Use a resistor with this Module. The one in my kit did not have resistors added.
This page will contain information for the HW-477 Two Color Common Cathode RG LED Module. It will include pinout and specifications. There also will be links to the projects that leverage it.
The “Cathode” pin is the ground/negative pin. By also supplying positive voltage to one of the other pins you are able to turn on the LED. Note that you can supply positive voltage to both of the other pins and get a yellow/orange color.
| Pin | Description |
|---|---|
| (-) | Ground (ADD A RESISTOR) |
| R | Red LED |
| G | Green LED |
