# Arduino Core

Arduino Core подходит для первых labs, потому что быстро дает feedback loop: write, flash, observe, measure.

## Use For

- Blink
- Button input
- PWM LED dimming
- I2C scanner
- LCD test

## Notes

- Board selection must match actual ESP32 dev board.
- Serial logs are part of debugging, but physical measurements still matter.
- Secrets must not be committed.
