Remember a Counter After Reset
Persist state across power cycles.
A Counter That Survives
Let's build a press counter that remembers its total even after a power cut. We'll combine debouncing with EEPROM storage.
The Plan in One Line
On startup, load the saved count. On each clean press, add one and save it back. Simple, but powerful.
