This is a detailed tutorial how to play an audio sample stored in the program memory of the ATMega micro controller used by the Arduino mega 2560. It is also applicable to other Arduino types and stand alone AVR MCUs.
More Sophisticated solution will follow in the next part.
Used software:
Audacity - audacity.sourceforge.net
bin2h alternative - bitluni.net/2016/12/19/no-more-bin2h-exe
Arduino IDE - arduino.cc/en/Main/Software

This tutorial show how to build a mini handheld game form a
WeMos microcontroller and some shields. It constist of an OLED screen a buzzer for sounds and runs on a battery. It also shows a basic stand by functionality unsig EEPROM and deep sleep.
The case is designed with Blender and 3D-printed.
The game is fun to play and the code be found here:
