Quiz for fun, I/O pin and 4 levels Also many years ago, I have seen a similar thing done with a scope, using upper 8 bit of address bus as one axis, and lower 8 for the other.
I can only assume it wasn't all that...

Controlling relays using ESP32 Serial drivers would be the best way, IMO. Allegro used to make some dedicated serial lamp/relay drivers, but I'm not sure if they're still available. You might have to use logic...

Creating Beeps of different tones In my experience, most "passive" piezo buzzers can be persuaded to produce tones other than their resonant frequency, but the amplitude is a bit hit-and-miss.
The piezo devices...

Here's a clue...
PORTA &= 0x0f;replaces your four lines of code
PORTD &= 0xf0;
replaces the other four
Added to which, there's no reason...

tinyAVR (1617) strange sleep current draw #define F_CPU does not change the physical clock speed(unless things have moved on in recent years).
What IS the actual clock speed?

Glad you fixed it, but how was the F_CPU definition affecting input buffers?
