# Joystick Display

Day 69 of the 100 Days 100 IoT Projects collection. Board: Pi Pico.

A KY-023 joystick's direction renders live on an SSD1306 OLED with the Pico 2. Visualize analog sticks in pixels.

## How it works

The KY-023's X and Y voltages are sampled and converted into a dot position on the SSD1306 OLED, with a center marker for reference. Tilt the stick and the dot glides across the screen — analog input made visible, pixel by pixel.

## What you'll learn

- Analog input visualization
- Direction vector mapping
- Live OLED feedback
- Input device testing
