+/** 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.
