# Hint Box
Hint Box is meant as a game for kids where they look for hidden iButtons and get additional instructions/hints for each new iButton they find.
So far the instructions are hard-coded and every new game requires rewrite of the messages and button mappings in the code and recompiling.
## Hardware used
- Arduino Uno
- LCD Keypad Shield
- [iButton Reader](https://www.aliexpress.com/item/TM-probe-DS9092-Zinc-Alloy-probe-iButton-probe-reader-with-LED/32702820667.html)
- Resistors 4.7 kΩ and 180 Ω
- optionally some batteries and switch to make it mobile.
### Wiring
- iButton Reader DATA (Green) -> Arduino pin 2
- iButton Reader DATA (Green) -> R 4.7 kΩ -> Arduino 5V
- iButton GND (Red) -> Arduino GND
- iButton Led + (Black) -> R 180 Ω -> Arduino pin 3
- iButton Led - (White) -> Arduino GND
## Software
If you plan to re-use this game go to ```src/main.cpp``` and modify the messages in ```msgs[]``` and the iButton mapping in ```address_map[]``` and recompile.
Addresses of all iButtons scanned are printed on serial at 9600 baud. (... just in case you need new to know the OneWire addresses as Hint Box recognizes them)
## FixMe
- Due to the memmory limitation of the Arduino UNO the number of registered hints is limitted to approx. 10 (based on their lenght)
