Repetitive tasks in video games often find a way of pushing our buttons. [Facelesstech] got tired of mashing “A” while catching shooting stars in Animal Crossing, so he set out to automate his problem away. After briefly considering rigging up a servo to do the work for him, he recalled a previous effort that used an Arduino Teensy to automate a bowling mini-game in Zelda: Breath of the Wild and decided to use a microcontroller to catch stars for him.
[Facelesstech] programmed an Arduino Pro Micro to fake controller button presses. It starts with a couple of presses to identify itself to the Switch, before generating an endless stream of button presses that automatically catch every shooting star. Hooking it up is easy—an on-the-go adapter allows the Switch’s USB-C port to connect directly to the Arduino’s Micro-USB port, even supplying power!
[Facelesstech] also designed a compact 3D-printed case that packages up the Arduino Pro Micro along with an ISP header for easy updating. The case even lets the Arduino’s power LED shine through so you know that it’s working!
If you, too, need to automate video game button-pushing, [Facelesstech] has kindly uploaded the source code and 3D designs for you to try. If you’d prefer something a little more low-tech, perhaps you might try a mechanical button pusher.

The Pokémon games have delighted legions of Nintendo gamers over the years, and show no signs of slowing down any time soon. Despite its popularity, there are certain aspects of the games that are unarguably about simply grinding your way to success. For [Mori Bellamy], this simply wouldn’t do – yet their thirst for gold bottlecaps was insatiable. What to do? Automate it, of course.
The first step was to hack the Joycons from the Nintendo Switch. A DG333A analog switch IC was hooked up to the buttons inside, and controlled by the GPIO pins of a Raspberry PI. The joystick was then controlled with an MCP4725 DAC, allowing the system to fully emulate control inputs to the console.
With the console now under control by the Raspberry Pi, the next step was to add intelligence. Google’s Tesseract OCR platform was combined with a helping of Python code. This allows the script to read dialog boxes from the game, and use this data to determine which buttons to press to farm items.
[Mori] has provided the code on GitHub for others to use, noting that it should be generalizable to other games with a little work. Fundamentally, the underlying hardware could readily be repurposed to other controllers, too. There’s plenty of other ways to automate the drudgery of gaming, even if you have to use a touch screen. Video after the break.
