G+_J. Peter Haliburton Posted December 23, 2017 Share Posted December 23, 2017 I've been doing some Know How inspired shopping lately, and made my first Arduino flash a light. And so it begins... Link to comment Share on other sites More sharing options...

G+_J. Peter Haliburton Posted December 24, 2017 Author Share Posted December 24, 2017 Yes, Dan Hockey, and especially when a 3D printer is added next year. Link to comment Share on other sites More sharing options...
G+_Bob Shields Posted December 24, 2017 Share Posted December 24, 2017 "next year"? I did the same thing: I bought an Elegoo Arduino kit and began playing around. Then I bought some Nanos to make smaller packages with. Then I realized I needed a box to put the projects in, so I'm now the proud owner of a CR-10 3D printer. I really hope Fr. Robert Ballecer, SJ publishes the Tinkercad files for all his projects (including the ones from KH250 which seem to have been lost...). Link to comment Share on other sites More sharing options...
G+_Chris O'Riley Posted December 27, 2017 Share Posted December 27, 2017 Now you've done it. Arduino's have been the cause of many 'a lost hour of sleep. You start fiddling with something, download a few data sheets which you try to make sense of, and next thing you know, it's 3am and your wife is standing in the doorway in disbelief that THIS is what has kept you from coming to bed all night! ;) If you don't already have one, pick up a small multi-meter, they come in real handy.

G+_J. Peter Haliburton Posted December 27, 2017 Author Share Posted December 27, 2017 I have multiple multi-meters, but a couple more wouldn't hurt. :) I did buy an iGaging IP54 caliper which didn't make it into the picture. The MP Mini Delta 3D Printer is sitting in a wishlist awaiting availability. There may be some Nanos ordered before this week is out. Not tried coding from scratch yet, since there seems to be lots you can borrow from. Besides the light, I did get the distance sensor working. Probably try varying the speed of a motor next. Yes, some sleepless nights ahead. Link to comment Share on other sites More sharing options...
G+_Chris O'Riley Posted December 27, 2017 Share Posted December 27, 2017 Nanos are great, plenty of IO, built in USB port. I use them almost exclusively when prototyping and then switch to something else for the final build, Pro Micros or just a bare ATTiny chip if I'm only using a few IOs. I wouldn't worry about coding from scratch. As you say, there's so much you can borrow from, and I think you'll learn more and more quickly by seeing and using what other people have done. Over time, you just pick things up naturally. Speaking for myself, there's no way I would have figured out how to do things like change registers on i2c devices if I didn't graft someone else's code into my sketch and then poke around until I understood how it was working.
