Just getting back into Arduino and puzzling over this probably basic point. In my main loop I have an if. Its condition is met and an LED switched on, followed by a delay of 4 seconds, then the end of the if and the loop. But the LED (and its 220 ohm resistor) appears to be getting only about 2.5V.…

Does a delay inside an if() pause loop?

have you set pinMode?
show your code.
