Add the code tags, please. "< code >" editor button.
On line 18 there is the error of invalid use of void expression
Try again, CODE TAGS:
Tic_WifiLed function expects 2 arguments. ParpadeoLedWifi( ) is invoked, expecting it to return a value, but it is defined as void.
by any chance does Tic_WifiLed expect a function pointer as a 2nd argument?
or are these parameters suppose to be specified when Tic WiFiLed is declared?
Shouldn't it be
Tic_WifiLed.attach(0.2, ParpadeoLedWifi);
