Not sure if this is the right spot to post this.
I am currently working on some kind of thermostat using Blynk and arduino.
For this I needed to use the SimpleTimer library.
I installed this library following the instructions but when I try to compile my sketch I get following failure remark:
In file included from C:\Users\tom\Documents\Arduino\IOT\Thermostaat\Thermostaat.ino:1:0:
C:\Users\tom\Documents\Arduino\libraries\SimpleTimer/SimpleTimer.h:11:24: fatal error: functional.h: No such file or directory
I thought it was because of failures in my sketch but when I am trying some exampes of the library itself,I get the same.
Does somebody have experience with this kind of issues?
