I'm building my own A320 cockpit. I'm starting with the FCU, which is pretty challenging, but if I can do this, I will have learnt a lot to start the real project. I'm making a mockup right now. I'm having a Snapmaker 2.0 A350 allowing me to 3D-print, CNC and laser engrave. I have knowledge about electronics and software (C, C++, C#), and have already developed a software suite that allows connecting my panels via a PIC Microcontroller, using USB. So far so good. For the backlight of my panels (using painted opaque acrylic of 5mm in which I engrave my characters/symbols), I plan to use white LED. I might need quickly 10 to 20 LED's of which I plan to control brightness using PWM. I know that connecting multiple LED's can be done in series or parallel, and by eventually using driver chips. But I'm looking for some practical examples/schematics by somebody that has already done this before me. Anybody here that wants to share schematics and concepts for LED-backlighted panels? Thanks in advance!

I'm building my own A320 cockpit. I'm making a mockup for the FCU using 3D-printing, CNC and laser. Electronics and software are already working on the FMGS add-on. What I was wondering is if there are ways to control the light output of all the elements in a cockpit. See below picture identifying 5 elements. 1) Intensity of indicators related to SPD, HDG, ALT and V/S 2) Intensity of 7-segment display 3) Backlighting of panel 4) Permanent indicators of Korry switches 5) Status of Korry switches As I think that 1) and 2) in a real A320 is based on LCD-panel with backlighting, it's probably an irrelevant question. I can also assume that 3 and 4 are controlled together. Might even be that there is nothing to control at all, and all is defaulted to a certain intensity. Just curious...
