A quick search for arduino fuses programming turned up a bunch of results:
So I came across this ASX00031 Breakout Board. Not gonna order one today, but looks like it might be the sort of thing that would come in handy.
I’m gonna try one of these Arduino Nano knockoffs: Upgraded /NANO V3.0 ATmega328 Extended Compatible for arduino ATTINY88 Micro Development Board 16Mhz /Digispark ATTINY85. They seem to be an ATtiny88 in an Arduino Nano form factor.
There are cases for the Nano, but they’re not cheap: Zebra Classic Case for Arduino Nano.
I’m planning to get a bunch of these: 0.56 Inch 7 Seven Segment 4 Digits Red Clock LED Display Common cathode Time 12 Pins. Then I need to figure out how to drive them from an Arduino Nano…
