/** Looper function
* functions used for Ticker and Timeout should be of type void <name>(void)
* i.e. no input arguments, no output arguments.
* if you want to change a variable that you use in other places (for example in main)
* you will have to make that variable global in order to be able to reach it both from
* the function called at interrupt time, and in the main function.
* To make a variable global, define it under the includes.
* variables that are changed in the interrupt routine (written to) should be made
* 'volatile' to let the compiler know that those values may change outside the current context.
* i.e.: "volatile uint16_t emg_value;" instead of "uint16_t emg_value"
* in the example below, the variable is not re-used in the main function, and is thus declared
* local in the looper function only.
