"Magic 8 Ball" toy project

Arduino (ESP32-based) project for digital implementation of "Magic 8 ball" toy

Features

This digital toy project offers many nice features unlike similar ones:

multiple languages support
synthetic voices
realistic (or "realistic" 😉 ) animations
gesture-based user interface
"deep sleep" functionality (for better power consumption)

Parts

Name	Link
ESP32 development board	eBay
TFT IPS Display 1.3'' 240x240	Amazon
DFPlayer Mini	eBay
16GB micro sdcard	Amazon
MPU-6050 Accelerometer & Gyroscope Sensor	Amazon
AAA battery holder	AliExpress
Short micro USB cable	eBay
Push button	Amazon
Original "Magic 8 ball" toy (for case)	Amazon

Note: I believe, you can find better parts pricing on Ali/eBay etc. And I already had many of these parts before starting this project.

Circuit

Zoomed ESP32 <-> Display connection (please note, different display type might require different connection scheme)

Also, here is YouTube video for connecting ST7789-based displays to ESP32

Note: you may want to add some resitors (for pulldown serial communication) or capacitors (for VCC). However in my case everything works "as is" 😉

Building Arduino sketch

You should add a few extra libraries to Arduino IDE to build this project (see project includes)

For voice files generation I provide a small console utility GenerateVoices. Build it using VisualStudio (or download from Release section), and run from command prompt:

GenerateVoices.exe [full_path_to_Arduino_sketch]

i.e.

GenerateVoices.exe C:\repos\magic8ball\magic8ball.ino
