You can make a new class , create a task to control blink or not, and color, with only one function call in you main code . I have done it, but is on vacation now, so cant share it.

@davelondon No

@david-bethesda you select where to write the text, x & y, then make a function to first erase the area with fill rect and then write the new text at x,y

@david-bethesda the short answer is yes ;-)
You Will have to make you own wiring/cable , then if using Arduino programmering find a library supporting the sensor, upload example code and test it 😉

@testing123 it is the program you have loaded in the Core 2 who control the speaker, so you need to change the program.

@spjrc set a timer to call a function after 6-12 houre, then call ESP.restart() from that function.

You can reboot esp32 using ESP.restart();

@meirmark the answer is both, just checked the library it use Wire.h so you only have to use the correct pins in the setup Calle.

@meirmark I code All my M5Stack pruduct using Arduino ide with added M5 support, so the library work for me.
