The Raspberry Pi should have some access to internet connection 🌐 in order to communicate with our game server hosted on Heroku. In order to complete this step, refer to Section 6.1 in the tutorial linked below:
Next, skip to Section 9.1 of the document to install Berryconda 🍓 onto your Raspberry Pi. This will be needed to create a Python virtual environment and install the necessary packages to run our gesture classifier. 💪
Our gesture classifier requires the BerryIMU v3 in order to properly function. In order to send accelerometer and gyroscope data to the Raspberry Pi via I2C communication, refer to Section 2 in the tutorial linked below:
To further enrich the user experience, we whipped up a drawing tool made of a small breadboard with a push-button, and an orange pin-pong ball for color detection. Whenever the button is pressed and held, you start drawing on the canvas! Otherwise, the game does not pick up your "air-strokes". 🍃 This simulates the "feeling" of drawing, and makes drawing a lot more robust!
In order to "build" 🔨 our custom drawing tool, you will need the following components:
The circuit for the drawing tool is pretty simple! It utilizes one of the Raspberry Pi GPIO pins to sense a button press seen in the circuit schematic below:

The female jumper wires should be connected to **Pins 39** and **40** as seen above!
