Dungeons and Dragons Hit Point Tracker With E-Ink Display
thingiverse
A DIY project for my Hit Point Tracker with E-Ink display. It utilizes an Arduino Mega 2560 and HC-06 Bluetooth module, as outlined in this Instructables tutorial: https://www.instructables.com/id/Dungeons-and-Dragons-Hit-Point-Tracker-With-E-Ink-/. My goal was to design a hit point tracker that displays players' hit points in a normalized scale, making it easy to identify who needs healing the most and how poorly the party is performing. This tracker connects via Bluetooth to an Android phone, providing all necessary buttons for controlling party status. It runs on a replaceable 9V battery, with its current state saved to EEPROM, ensuring no loss of hit point values when swapping batteries. Required components: - Arduino Mega 2560 - HC-06 Bluetooth module - 400x300, 4.2" E-Ink Display Module - RobotUI app from the Google Play Store - Three resistors, all with the same value - 9V battery - 9V battery connector - Wires and solder - (Optional) Some kind of case - (Optional) Power switch for convenience - (Optional) Cylewet 55 breadboard for those who hate soldering Tools needed: - Soldering iron - Wire cutter - (Optional) 3D printer for custom cases
