Personally a keyboard matrix is really only useful for a full sized keyboard, but even then you could buy a larger microcontroller such as a Teensy 3.5. I think it'd just be fun to try, but I'm not sure how effective it is other than organization of wires.The scalable code is a great idea though! I'm still learning c++ and the arduino ide but I'm sure I could adapt what I know about java, and make a class for objects of switches instead of all the if statements. I'll try it out!
I really only need the 6 keys. This is a small part in a larger keyboard, where everything is modular, so I really did mean to base the macropad off of the arrow keys. I never really needed a matrix, as I already have enough pins for the switches, even for the full keyboard, so the matrix doesn't seem beneficial. Good tips though!
It definitely would be possible, but you'd probably need to increase the size of the case to fit a bluetooth shield and battery. From what I see also, you might need to remove the OLED display as it might interfere with the communication. I'd research it a bit more and see what pins the bluetooth shield would use to prevent interference, maybe research a different microcontroller as well, as different micro controllers might not have the interferance that I experienced
I wonder that to. I don't know how popular they would be, and I'm not sure how I would work things out like shipping times and cost, but maybe I should try it with etsy or something?
It can really be used for anything. Most of the time, it will be used if you just need a few extra buttons, or want some macros to simplify editing videos or creating a 3d file.
I'm not really that experienced with things like that. It's most likely possible, but you may need to combine this with another Instructable or project. Try doing some research if there is a shield or something that would be able to send a 5.8 GHz signal with a Arduino, then use this Instructable for the build. Maybe you could have it transmit to a computer that would transmit the signal to the drone, although I know that'd be inconvienient. Sounds like an intriguing project!
I know my prints aren't the best, but that's because I still need to fine tune it. I've improved them a lot, but I'm not super stuck up on the quality. For something like this, it does me well, but with previous prints I've put layers of primer. It all depends on what the print is for, plus for something like this, I don't really want paint on this, for the smell, and chipping, even though I know that you can get rid of those.
Yup, It just connects with a USB port, it acts exactly as a keyboard. You can make it without the OLED as well, just skip the OLED step and remove the OLED code from the final code. You might want to modify the files too, so you don't have the empty spot, but otherwise it is possible!

So, as somebody who doesn't know much about this, but wants to give it a shot at building a operating system... Is it possible to build a game into the operating system? Like having Mario jump on a program to launch it? This will probably never come into fruition, but it would be fun to try. But does anyone know if it's possible?
