For my next board I want to do a stepped caps lock and put in an LED indicator to show when caps is on or off. I have seen a Wildcat video where he kind of does this but it’s not explained at all. In video it looks like he takes little Mill max sockets and solders those to the caps lock position on the board and then puts the switch on the board. He then puts the LED legs through the little slot on the switch and into those mill max sockets on the board.
Questions:
1. Are these positions on the PCB that support through hole LEDS (like Caps lock, scroll lock, etc.) already set up and working when they ship the board to me? Meaning, can I just solder a LED to this position and it will automatically work when toggled on and off?
2. If its not already set up by the manufacturer what do I have to do to get it working and can I use VIA to do this.
3. On LED, one leg is longer than the other. Which leg goes in which hole. I don’t have a PCB in front of my but I think I remember that one of the LED through holes is in the shape of a square and the other is a circle. Do I put the longer leg through the square hole and the shorter one through the circle? I just don’t know which leg is positive or negative.
4. If I cannot use VIA then I assume the only thing to do is use regular QMK and how would I go about programming the LED
My first board was the Drop Alt and honestly QMK just looked like a headache so every board I got after that I made sure used VIA so I didn’t have to mess with Hex files and flashing boards and all that other crap. Some clear information, or some knowledgeable help on this topic would be greatly appreciated. Or if you know of a good YouTube video to point me to that would help too. Thanks in advance.
