In Need Help?
I keep reading different things online and am curious what you have found to work without destroying your boards. Some places, such as here say max of 40 LEDs If these are all 20mA that goes over the 500mA limit draw from the USB port doesn't it? Does that require a separate power supply then? Secondly, if I look to use some dual brightness features for a few of these annunciators, is drawing 40mA for a short period from a single pin going to cause issue? (The transition stage for the blue annunciators). Would you do this with two pins and some diodes so you have two different outputs one for bright and one for dim, or would using PWM and just a single pin make more sense? Maybe I should stop reading and just do it, planning on using 6 arduinos for my forward overhead so I believe I should have enough ports. Thanks in advance. Jason

In your video for your aft overhead panel, you used these very handy forms for the LED so there wasn't any overlighting from the neighboring LED's. Any chance you can post the STLs for the LED holder and cap? It's around 10:50 in your aft overhead video Thanks in advance.
