BlynkTimer allows you to send data periodically with given intervals not interfering with Blynk library routines Blynk Timer inherits SimpleTimer Library, a well-known and widely used library to time multiple events on hardware. BlynkTimer is included in Blynk library by default and there is no need to install SimpleTimer separately or include SimpleTimer.hBlynkTimer object allows to schedule up to 16 timersArduino 101, Intel Galileo, etc.loop), it just skips all the missed intervals and calls your function only once. This differs from SimpleTimer, which could call your function multiple times in this scenario.BlynkTimer can schedule many timers, so most probably you need only one instance of BlynkTimer in your sketch.
