I have a set of LED strips that have the following four wires:
- Red Channel
- Blue Channel
- Green Chanel
Given these wires, I can produce the following colors without additional components:
- Purple (Combine red and blue.)
- Cyan (Combine green and blue.)
- Yellow (Combine red and green.)
- White (Combine red, green, and blue.)
However, the control module (now fried due to a crossed wire) has an option for amber/orange. The question is, how can I produce this color? I believe I may have to combine green and red to produce yellow, and add a resistor or similar to the green channel to reduce the current to that color thus displaying more red and possibly producing the desired color.
- The lights are powered by a 12v source (car battery).
How can I use the above to create an amber/orange color from the lights?
If the answer is simply adding a resistor, what is the lowest resistor I should use in the 12v circuit?
