How I can do so that my potentiometer is linked with an LED to be able to control the ignition and append and vary the intensity of light. Please
With code of course … Google for some of the thousands of examples, then simply add in Blynk as needed to use the slider widget or something else instead of your Pot.
first you need an AC Light Dimmer Module for PWM control and a blynk slider.
very easy sketch
For an LED?
if it is just for one led I 'm stupid
I thought he had a LED light bulb, else no need blink for a led !
better use this rehostat
