A handy hint? or not. Blink without delay 3.0.

WizenedEE:

static uint16_t _lasttime, uint16_t _thistime

According to the standard. 6.5.3 - 3

If the for-init-statement is a declaration, the scope of the name(s) declared extends to the end of the for-statement.

But I see the static now, :frowning: . hmmm
