First picture is just the Arduino and PS/2 connector, second is the entire pcb. Not sure the best way to upload the whole file. If that's needed, a link on how to do it would be nice.
I don't think the rest of it is relevant, but it's there. Each of the ICs are Shift Registers with resistors next to them. Each of the Sets of 4 through holes are 5mm RGB LEDs. The Sets of 3 through-holes are sliding switches. If I have to order new PCBs, does anyone know of an actual LED driver with resitors and/or brightness regulation that has 7 RGB outputs, or can be run in series? Not a necessity, but I'm sure there's a better way to do it.
Pins of PS/2:
3 1 2 4
5 ----- 6
D1 is the 2nd pin from the left on the bottom row of pins.
Yes, I did, but I didn't throughly test the bread board.... whoops... 33 Nano's "+5v" pin isn't 5v, despite trying different input voltages through the VIN... my 5V rail is connected straight to the VIN which is regulated to 5V.
If I were to get the PCB remade (sounds like I will), how might I get the components already soldered on? I saw SMD Service on JLC where I got the last PCBs, but I don't know how to add SMD components using Diptrace. Do I need a new program, or can I keep using Diptrace?
Thank you all for your help!!!
