Yes, but an Arduino is seldom part of that solution
space for the
low-power domain. Great for tooling around, yes, but you need to be
rather careful in doing low-power design.
I feel that the Arduino emobodies most of what's wrong with mdoern
hobbyist electronics. It implies that solutions are obtained by plugging
together fairly complex modules (whereas really elegant solutions are
almost always obtaiend by thinking in terms of simple components and
using the properly) and it implies that soldering is a complex skill that
you don;t nbeed ot learn (whereas I, and many others found it very easy
to learn, and it's essential if you want to go further with electronics).
