I’ll start with the link as that seems to be the first question:
First of all I just found this site and it is wonderful! I’m not entirely new, but I stopped for a few years and now I’m back to learning this stuff. I just love it, but my old brain has trouble figuring out the code. This is great to help know what components are needed to make stuff happen and code to get it going.
I built this with circuito.io and I need modify the code slightly to work more simply. I got it to work, after much frustration, until I figured out I had to input the number 1 in the serial monitor to make it run the test. But what I what to do now is get rid of the serial input and just plug it in or turn it on and the solenoid will activate every 4 mins. I know how to change the time in miliseconds, I just don’t know how to eliminate the test part of this code and get it to work. Also, is this a bit of over kill with the components? I just simply need the solenoid to activate every 4 mins or so. And, can I power it up with just the USB or Battery, do I need Both? I would prefer just the USB. I do have a 3.0 volt solenoid that I think is strong enough to do what I want if that helps.
Thanks in advance for your help. I saw a similar post but it was using a Raspberry Pi or something. I couldn’t translate.
