| 2 | + Microcontroller startup counter example with ESP32 Preferences library. |
| 3 | +
|
| 4 | + This simple example demonstrates using the Preferences library to store how many times |
| 5 | + the microcontroller has booted. The Preferences library is a wrapper around the Non-volatile |
| 6 | + storage on ESP32 processor. |
