That's true, the blue LEDs would ideally have a resistor closer to 4x than 2x when jumping from 3.3V to 5V. I don't remember my original…
Thanks for your reply! Your "roughly double" resistances for 5V vs 3.3V imply that the difference between LED drop and 3,3V is same as 3,3V…
Your right, that would be a great way to fine tune the current for LEDs! You're also correct that the goal of this project was finding the…
