I'm wanting to hook some LEDs up to my Mendel90, but I'm stumped when it comes to where to hook them up. I have the Melzi board that comes with the kit. I'd like to connect the LEDs to the Melzi, but also (if possible) control the LEDs through the use of 'printer interface' commands. If I have to, I'm fine with the LEDs being on all the time if the printer is powered.
Are the 2x3 and 2x5 connectors next to the USB connector usable? As in, power through those and control through the use of commands? I thought about connecting the LEDs to the fan port, but there are times when I want the LEDs on and the fan off. Any other options out there?
