Use delay(60*60000) to pause for 1 hour (60 minutes). 1 Day delay Example Use delay(24 * 60 * 60 * 1000) to pause for 1day. The Problem with Arduino Delay So far, everything looks great; Delays work fine and LEDs flash on and off, but delay() has a skeleton in the cupboard...

delay(30); } The sketch works by cycling the duty-cycle of the PWM output, which causes the LED to fade and brighten and then repeat. In order to work with our ESP32 hookup you will need to change the LED_PIN constant (on line 23) to a “2” instead of “5”, as our LED ...

With the help of the timer we can tell the microcontroller to do a given tasks again and again e.g. after 1000 microsecond. You cannot use the delay function to pass time as this would interrupt the important call to the Blynk.run(); function which is located in the loop part of the...
