SpellBook

Tabletop SpellBook for Dungeons and Dragons 5e.

This Arduino project keeps track of spell slots and spell text without having to have a phone out, spell cards, or a stack of paper/book.

Hardware

• Adafruit M0 Adalogger
• Adafruit Sharp Memory Display Breakout Board
• Adafruit 8x8 Mini Led Matrix with I2C backpack
• 2.7" Sharp Memory Display replacing the one that comes on the breakout board
• KY-040 Rotary Encoder
• 19mm Push Button
• MicroSD card

Software

• Currently, spells data is stored in a JSON file on an SD card and parsed into spell objects in the program.
• The rotary encoder rotation moves through slots and levels (depending on rotation direction)
• When you click the encoder button it will switch to the spell side, where rotation rotates through the spells.

3D Printed Shell &

• 3D printed shell is in two parts. The base still needs some work, I would like to line up the USB to the hole in the back.
• M3 Thumb Screws amazon link
• 50mm donut semiprecious gemstone pendant for the knob eBay link
• 18x25mm semiprecious oval cabochons for the upper back panel amazon link

Future Plans

• Add a way to do long rests
• Adding a way to mark spells as prepared prepare spells to shorten the list.
