Master Grumpy_Mike,
I have some last (hope) questions...
I found a pretty 5V 2,5A as I wrote.. (my father kept it in his messssssy office)
I'm designing a PCB: http://www.flickr.com/photos/julien-bayle/2875013886/
- a couple of components 164, 165 will take them supply on arduino (via USB...it will be very enough)
- the famous backpack LED Driver will take his need from the external power supply...
for this last item I have some question:
- should I use capacitor between gnd & Vcc ?? how could I calibrate them?
- ok for linking of Gnd... BUT, how it goes? Directly on the PCB?
help would be appreciated.
so, the good news of the week is: I received the pretty enclosure parts for my gear:
