Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: “DOIT ESP32 DEVKIT V1, 80MHz, 921600, None”
Sketch uses 631346 bytes (48%) of program storage space. Maximum is 1310720 bytes.
Global variables use 37960 bytes (11%) of dynamic memory, leaving 289720 bytes for local variables. Maximum is 327680 bytes.
