Using millis() in Blynk

I need to blink it at certain intervals without using delays

C++ Blynk (Legacy) - Code Examples for Basic Tasks

#25 - Das Timed Blinkin’ LED… Without any delay() - AKA Timerception This is simply just two nested Lambda functions using BlynkTimer and two different timer types to flash a Virtual LED ON for 1 second and Off for 1 second… If this is placed in the void setup() it just repeats in the background… marquee style. Here it is integrated into a bare bones Blynk Blink Sketch… There should be enough commenting to figure it out from here. LED Widget set to V0 #include <ESP82…

#26 - Adjustable pulsing LED that fades in and out with Timers And now for more Timerception tricks… A variable timed, flashing (pulsing) physical LED that fades in and out, all with nested timers in lambda functions. One of the lambda tricks I had to discover, via trial and error, was using a “fixed call” interval timer called simply setTimer(long d, timer_callback f, int n) that will run its timed interval course as normal, but only n many times before stopping… the key was finding where to…

#28 - Dual LED Fade/Flasher for both Virtual and Physical LEDs Here is a simpler? or just more compact Dual LED Fade/Flash that works with both Virtual and physical LEDs. It uses two nested Lambda type Timer Functions with if() logic to determine which timer is running… all in one Arduino function (speed switching aside) UPDATE EDIT - I made some tweaks and added some 1ms delays in critical spots… it seems to work much nicer now and switch speeds smoothly… at least in my tests.

I think you can see my point
