This is the setup routine, it runs only once, every time the Arduino is started up. (void is a data type, it means no information is returned by the setup, more on this later. The two brackets are used in every function, to pass data through; setup doesn't need any data, so the...

Then, thebootCountvariable is increased by one in every reboot, and that number is printed in the serial monitor. ++bootCount;Serial.println("Boot number: "+String(bootCount)); Then, the code calls theprint_wakeup_reason()function, but you can call any function you want to perform a des...

You use theEEPROM.update()function as follows: EEPROM.update(address,value); At the moment, we have 9 stored in the address 0. So, if we call: EEPROM.update(0,9); It won’t write on the EEPROM again, as the value currently saved is the same we want to write. ...
