We’ve seen a lot of reset types, but never a brownout reset …
↓↓↓ Complete description, time index and links below ↓↓↓
In the last two videos we’ve talked about the different types of resets you can detect in your sketch running on an Arduino Nano Every, sporting a megaAVR 0-series ATmega4809 (links below). However, we’ve never seen a brown-out reset.
So let’s starve our Arduino of electricity to drive it into a brownout. But before that we have a look at the Nano Every’s power supply architecture, what’s on my breadboard and the sketch I’m running. Spoiler alert: Brownout but no reset
00:00 Intro – we’ve never seen a brownout reset
01:01 Power supply – of the Arduino Nano Every
04:49 Breadboard – already featured in last videos
05:34 Sketch – already featured in the last videos
07:46 Brownout – down to 3.5V VIN and up again
12:08 Summary – 5V rail goes first, then the 3.3V
13:42 Wrap-up – megaAVR brown-out detector, bye
