+This is a tiny little project I made to get my own Virtual Pet. I hope you like it as much as I do.
+The code can receive some optimiztion, so feel free to change it as you like.
+I would be glade to see your project too if you choose to make one pet by yourself.
+Thank you!
+
+HARDWARE:
+- STM32 F103C8T6 (Blue Pill); (It demands at least 3.5KB RAM and 32KB ROM)
+- 1.3" OLED I2C Screen 128x64;
+- 4 push buttons (with 1n4148 diode to prevent debounce);
+
+WIREING:
+I Used the pins PA9, PA10, PA11, PA12 for all the buttons, and used a diode n4048 to prevent debounce.
