Steve hi, after making your SP10 clock (great design, see picture) I started designing my own clock using your motor controller. The idea is that the seconds would be a separate dial with Geneva mechanism (see attached picture). In order to make it more alive I want each cycle to be 20 seconds so it moves faster.
I am currently using the SP10 RPM. I want to triple the RPM. Can you please help with the correct numbers I should replace in the code?
