I am working on a headless Raspberry Pi project. Being headless, I can't visually tell when the system is fully booted and ready to accept tasks. While a Pi doesn't take an inordinate about of time too boot, I am still looking at 30-seconds or so.
What I would like to do is have a bi-colored LED (red-green) that would light up red when when power is applied to the system, but, when the system is ready, my task will pull a pin either high or low, as needed, to switch the LED to green. I do not have any components yet for this part of the project, so I am flexible if it is a two-lead red/green LED or a three-lead red/green LED.
The coding part, I have down. What I could use help with is the circuit.
