Decide that a coffee timer would be useful. Just an LED that turns on for a minute or two and then turns off. That sounds like something I could use that 555 that's been in my drawer for years for, so simple. One shot 555 timer. Easy.

Spend an hour getting all the jumpers and breadboards and components out and make sure all 20+ connections are correct.

Perfect.

It only works half the time and triggers when it shouldn't the other half. Swap component values to see if anything improves. Calmly disassemble everything and return components to their respective bins and certainly not dump everything into the 'to be sorted' bin.

Tell ChatGPT to write arduino code for some WS2812B LEDs and a button

Don't check the code just upload it, hopefully you told ChatGPT your Wi-Fi name and password!

Oh cute it even made the buttons coffee colored
