#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.
