Why is this linking to what appears to be another link aggregator, rather than what appears to be the original blog post?
Now try debugging on a microcontroller with none of that UART stuff Arduino gives you. Print statements? Ha, try debugging by blinking an LED.
LED? Luxury! 😁
I had one board with an improperly loaded power supply and I could tell what it was doing by the pattern and pitch of the squeal.
It did have a debug UART though, but I did come to find the sound pretty useful too!
Heh, kinda like knowing if your 56Kinda modem got a good connection or not.
