Several months prior to the annual Berkshire GeoBash Mega Event in Massachusetts (USA), I was contacted to see if I’d be interested in creating a gadget cache for their event. I said “Yes!” of course. I never dreamed it would end up as a top-ten favorited cache in my state.
When using a servo, does it bounce around a bit? Move when it’s not supposed to? There are a few things you can try to fix this problem.
I actually built this cache last summer, but still get tons of requests for instructions on how to make it. I didn’t document everything as I went, but this should help people who are interested in building something similar.
I enjoy building complex caches (and series), but I’m thinking most of my caches don’t have a broad appeal. I’m going to try and change that with a straight-forward traditional gadget cache. Spoilers follow! You may want to skip this article if you live in/near Massachusetts.
You’ve completed all your testing and your Arduino code is working perfectly. It’s now time to add your circuit to your cache container. Without the Arduino plugged into your computer, how are you going to power it?
For my first Arduino Gadget Cache, I wanted to use LEDs. I spent a lot of time searching for just the right lighted buttons and working through prototypes. It looked great in my shop. I took it outside for a weathering test, and I noticed that the LEDs just weren’t bright enough under the sun!
I’m somewhat new to using an Arduino, but am a software developer by day, so that’s helped my learning a bit. I have a woodshop in my basement and have made some craftsman style furniture as a hobby. I’ve translated those hobbies into cache container creations.
