Afternoon everyone! Looking for some guidance on a project I would like to create.
I'm trying to create a smart gadget geocache using 2.8in touch screen, a MEGA2560 board, and multiple sensors. It would involve opening a box, installing a 9v or another power source, turning it on, the screen would come on and display a personality quiz. Users would answer 5 multiple choice questions with points assigned to each answer. Depending on the total amount of points computed it would then turn on an individual sensor based on the score the user received. Another sensor such as an RFID module where the user would just swipe the RF chip across from it and then a number would pop up on the screen giving the combination to a lock. Then the user would be able to open up the geocache and be done.
Is this realistic to be done? Or am I just dreaming of something? We have the time and the spare cash for the tools or devices needed but I just want to find out if it can be done. Any help would be greatly appreciated, thank you!
Are you suggesting that people looking for geocaches will need to carry with them some kind of 9V power source , in which case your idea is not realistic.
Geocaches need to be self contained and not require any hardware input from the people looking for them.
Putting around $100 worth of small, easy to carry hardware in a remote location, for unknown persons to find, sounds a bit risky.
Actually @mauried thats what happens at most every gadget cache. The cache page will tell geocachers to bring a power source, ie AA, 9v’s, etc. This guy is popular for the many gadget caches he has and several of them we brought batteries too. You might have never heard of them or seen only the traditional caches. If you do a search for smart or gadget caches you will find PLENTY of them: Gadgetcaches - YouTube
@jremington...true but that’s why we will be securing this cache in front of our home. So it will be extra safe. We definitely wouldn’t want it stolen from some random spot in the woods.
I have the same worries as the others. touch screen ? why not some buttons ?
you could even bluetooth the questions to the visitors smart phone.
based on what you outlined, you should be able to make most, if not all you listed.
Weatherproofing is the main problem that I see. And some protection for the touch screen may be a good idea.

I see many geocaches in my area. I live in a State Forest and there are many that are drive-by ones.
one of the things I though about this one is my hand crank flashlight. why not have a hand crank to charge a cap
could add to the fun of the find.
