Tonight I’m making a little Arduino mains relay timer. It’s for the box fan in my room. The timer built into the fan broke years ago but even before it did, the ticking noise was distracting when trying to go to sleep! But leaving it on all night means I wake up extra dehydrated. Hence, an electronic 2-hour timer for my fan.
@kirby you know what, I think tomorrow I’ll change it so pressing it while it’s on does turn it off. Doesn’t hurt to have that option.
