How to make the voltage of the RGB LED's green and blue higher in this circuit? Answered
So I have two 5mm RGB LEDs. In my schematic diagram, RGB LED 1 is common cathode, while RGB LED 2 is common anode. My LEDs config is this:
Forward Voltage: 2.2V (R), 3.2v (G), 3.2v (B)
Forward Current: 20mA
I think it's the same for both? Of course when I send data from the PIC pins, one will turn on and the other will turn off. I used the resistors for current limiter. Please refer to the photos, when RGB1 is on (RGB2 off) the voltage are ok. 2.2v, 3,2v,3.2v RGB respectively. But when RGB2 is on (RGB1 off) the readings are 2.7v, 1.7v, 1.7v. It lights up in proteus. In hardware, the GB of LED2 will be dimmer right? or is this just ok? How do I increase the voltage here without affecting the current much. The current readings are also in the photos by the way, 16mA is ok I think.
I'm not very good with circuits so can somebody please give me the computation for increasing the voltage? Thank you. I'm trying to understand how it works. Any suggestions, criticism is ok LOL. Thaks! ^^
