Hello everyone,
This is my first post. I have a simple question regarding a Bi-color LED (Red/Green) with only 2 pins.
I am pretty sure the LED package contains 2 LEDs in opposite directions that will light up depending on the direction of current flow.
My question is, can I use 2 pins from a microcontroller to act as a ground and positive at different times? Green sometimes, Red at others?
Next question is the resistor.. Doesn't the resistor usually go on the side going to ground... I guess it would be fine if the resistor is on the positive side as well?
Does this make sense? 2 color LED with 2 pins... the pins would sometimes be positive and sometimes be negative depending on what color (red / green) I want.
