If I have a digital pin and it is set to HIGH, if the program the next time though sets it to HIGH again, is there any “blip” where the pin cycles from HIGH to LOW and back to HIGH or something else other than staying at HIGH steadily?
Here is what is going on. I am switching a solid state relay (25A) and want it to power a 250W metal halide light. (fish tank) When it is running off of the relay, the light will sometimes flicker or die. Otherwise, there is no problem. I do think that some interference in the electricity can cause this.
