Porygon consists of two parts: a digital circuit that is wired between a RasPi and a JoyCon, as well as a script to run that circuit.

For a video of it in action, and some tips on how to put this together, see the announcement post at https://invoked.net/2019-03-26-joycon-circuit/

• A circuit diagram
• An example implementation

The parts listed in the circuit:

To actually get the inputs going, you'll need shell access to the PI in your circuit. Then,

git clone https://github.com/moribellamy/porygon.git
cd porygon
python3 -m virtualenv venv
. venv/bin/activate
pip install -r requirements.txt

If your circuit diagram varies from the one documented here, there are some settings you can put in config.ini. This is if you didn't use the same pin numbers on your PI GPIO array, or if your power source isn't a clean five volts.

Then you are in control!

from porygon import *
import time

tilt_x(100)  # Go left a while!
time.sleep(1)
still()  # Zero out the joystick.

press(A)
press(X)  # And so forth.

For an example end to end script, which takes input from a webcam, read pokemon_lets_go.py.

More games and automations could be added. Use py.test to run all of the tests.
