Ardugotchi - A Tamagotchi Emulator on the Arduino

#

I found this project while browsing the Arduino Project Hub. Waves of nostalgia washed over me as I remembered my Tamagotchi from my childhood, a little dinosaur that I constantly overfed with sweets. Since I already had all parts needed for this project, I decided to build it.

How does it work?

#

Did you code a Tamagotchi in C++? No? Well, I didn’t either. The project uses a Tamagotchi emulator, you have to get the Tamagotchi ROM yourself and upload it to the Arduino. More info can be found on the porjects GitHub page.

Building the Ardugotchi

#

The project is pretty straight forward, you follow the circuit diagram from the project page and upload the code and ROM to the Arduino. I used an SSD1306 I2C OLED screen, three push buttons, three 1k resistors and a buzzer.

The Ardugotchi in Action

#

When you run it for the first time, you have to set the time. Afterwards you will be greeted by your new pet which hasn’t hatched yet.

After a few minutes, the egg will hatch and you will be able to interact with your pet.

As you can see, I immediately went back to my old ways and started feeding my pet. This time, however, I didn’t overdo it and my pet grew up to be a healthy adult.
