That 16-bit resolution thing - that could be what Ant was on about. Is it only one that supports 16-bit and the other two are 8-bit? Clutching at straws in my memory here, and I only read it last week

Yeah, looks like timer 1 can do 16bit but the other two only 8bit.

Thanks. I don't really care about having too many degrees of PWM. 0-255 is fine by me. Realistically 0-9 would do the job for the set brightnesses but would look crap for fading.

No problem. I was surprised how high the frequency had to go to not notice any flicker at all.
I waved my little strip around (YJ) and took a picture of it.

I've just installed the Android Arduino IDE. Maybe not a good idea, I'll never get anything done if I can work on projects with my phone. Uploaded the blink sketch to my Uno and it worked perfectly.

Shift registers and power supply have arrived so I'll be figuring them out tonight.

Floppy Organ now makes recognisable notes!
Learnt how to use interrupts tonight. Quite pleased with the progress, even though there's a lot still to do.

Saw some PCBs that a guy had made today by seeed, they looked pretty nice.

How do PWM outputs work with a shift register? Anything special needed for that?

Whilst you have to order a minimum of 5 them prices are actually fairly reasonable.
