I've read over the forum looking for an answer to my question but because I'm a beginner I suspect I won't even know when I run across it. I have a nano, I'm using Arduino 2.3.4 on Mac and I've managed to find a sketch that blinks an LED when a button is pressed, then shuts off the LED when it's pr…

The little popup on the forum here asked me to mark the post that was the solution to my question. I really can't. Alto77 worked with me throughout several posts to help me and I did learn how to do what I needed to do in this case. So technically, it's solved but will involve some reading if someon…

I'm not making much headway but I'm looking all over in C++ and Arduino tutorials, etc. to find the code that will get me where I want to go. I've learned that I can't add "const byte ledPin = 4;" right under "const byte ledPin = 5;". It causes dirty looks from the compiler. I read that const means…

[image] rushl: I'm not making much headway This is all hard until it is easy. I suggest you spend seven minutes on seven websites that turn up when you google things like arduino beginner c++ or arduino programming basics One or more of them may match your learning style, all the time…

Thanks so much for the information. I think I'm on the right path and actually enjoy the reading, as long as, like you said, it's not some dead end. The learning journey is one of the fun things for me, even if it is confusing initially. I'd much rather know the 'whys' than just being finished with …

Well, I'm getting somewhere! Even if it's not quite the destination. I've clumsily worked out how to make the domelight do something! I need to figure out how to base its state on when the flashing LED is going, I think. Right now, the dome light LED flashes (it's supposed to be solid on when the b…

I think I've almost got it! It works! Three hiccups; the flash rate seems kind of stuttered, if that makes sense, the second is that if I hit the button the 2nd time while the flashing led is lit, it stays lit and finally, the domelight led goes on/off with the button pushes but it ignores the time…

[image] rushl: it stays lit That could be a debounce issue... try this at 50ms or 100ms [image] rushl: if (millis() - lastButtonTime < 30) return;

@rushl … [image] rushl: case you were looking for a case of indigestion Not so much that as the kind of feeling you get going past a bad traffic accident. Sry, not really. But the two versions you posted don't seem to be what is running in the wokwi, and I swear that code changed right in f…

Sorry about the modified code. I did it that way mainly so someone could see the process I'm working through and the results, with the most recent one posted being the current one. I can see how it'd get confusing, though. This morning, I'm running it through my Nano and the weird flash rate is gon…

Got it!! Yay! There was a small typo in the piece of code that you recommended & that gave me an error but you mentioned earlier in the thread that the error generally will tell you what's wrong. It said something like it can't be called to or something like that. So, I figured it didn't recognize …

[image] rushl: There was a small typo Fixed that for ya. There are no small typos! I use a style for variable names that capitalizes internal words, so here I must have been thinking about domelight with no consistency. Is it a Dome Light or a Domelight? I tend to leave "pin" out of identif…
