So i recently had an idea for a Cryptex that uses an arduino. It combines a keypad, a .wav player setup for the Uno R3, and an LED that lights up to show if the device is playing any audio files. Im still a bit new at using an arduino, so im not all that sure how to make something like this work. Can anyone give me some direction on how to get started making this?
I don't know what a 'Cryptex' is but the interfaces you listed are all commonly used with an Arduino. I suggest you start with a UNO and a Wav shield and keypad. If you were thinking of using a local display, there are LCD shields that incorporate a keypad. Before buying the hardware, check that any/all shields you plan to use are compatible with each other i.e. all within the power limits of the Arduino, and don't have any conflicting pins. If you can't get around the pin conflict, your fallback would be to use separate PCBs for some of these devices i.e. connected by wires instead of mounted directly onto the Arduino.

Cryptex - Wikipedia Here's what a cryptex is.
Given that the Cryptduino would be similar in purpose compared to a cryptex, it would be different in functionality. The purpose is for a game thing, but it works like this:
The device would be given to a player or team and they would be given a code for the device. They enter it in, press a play button and the device would play a .wav message, giving the player/s instructions on what to do. Examples would be: where to go for what challenge to do, rules of a challenge, and etc.. Once they get to the challenge, there would probably be a code to enter to start the challenge, and if its beaten, they get a reward and a new code, informing the player/s where the next challenge is. This process would repeat itself depending on how many challenges there are to beat.
All in all, its a simple concept. But for the design of the Cryptuino, it would be strapped to the player's non-dominant arm. The dominant arm would be able to work the keypad and whatnot. Within the design of the device, i have yet to draw out how i would want it to look, but i know it would be quite bulky for the player to have a blocky chunk of electronics strapped to his wrist.
Ill draw up a quick sketch. That would help with the explanation.
I remember seeing several generic enclosures including one that provided a keypad designed to be strapped to a forearm. I don't remember the brand name but perhaps Google would find it for you - it sounds like exactly what you would want for something like this.
Something like this?
yeah! something like that would definitely work! and it would be somewhat sleek
