I need to use 2 or 3 color LED for my circuit.(preferably 3 color one). I am going to use PIC18F26K83 to control the LED. However, I am confused how am I going to make it change colour. I think I need to give different voltage values to it. (For 3 colour one it says: 1.9V Green, 1.85V Red, 1.9V Yellow) In this case what will it be if I give it 1.9V?. To sum up my questions are:
- What do I need to do in order to use make the LED to change colour? Do I need to change voltage value of it? If yes how can I change it? Via hardware?
I have a circuit for 2 colour LED and it works fine. Can I also use exact same circuit if I need to replace 2 colour LED to 3 colour one? Do I need to replace any components? (See the datasheets below)
Datasheet of the 2 LED's and circuit schematic are below:
