Known Good

Conﬁguration

Rule #1 of experimenting:

Before trying anything new,

Get back to a known working state

So let’s spend a few minutes & get “led_blink” working again

Get your entire edit->compile->upload->run working

Even if it becomes so second nature to you that you feel you shouldn’t need to, do it anyway.

Especially when mysterious problems arise, revert to a known state
