Oh, I actually use short delays at times when it doesn’t matter… but in this forum we do try to teach Blynk embedded, approved and comparatively easy to learn timing methods, without limiting to special MCUs.
Not that an ESP32 dual core tutorial is bad, perhaps overtly advanced for some, and not even required in most use cases. Not talking running Blynk on a full blown CNC here (although might be possible) I don’t see that as Blynk’s true purview.
I will give it a shot with my setup… meanwhile, I have introduced a full stepper control example for either ESP32 or ESP8266 (would work on Arduino as well), with just a single timer.
