Hi I'm quite new to c++ programming and I want to create and include a custom class to a esp32 project with eclipse?

But I just don't know how, I can't even create a class in the same file

hi, when I wait for something in the main loop like: void loop() { if(boolValue){ //boolvalue normall is false //do something } } would it spare a lot of power if I add some delay in the loop like: void loop() { if(boolValue){ //boolvalue normall is false //do something } //added delay delay(10); } ...
