 We'll create simple projects like displaying text and an image (display Ferris 🦀 image) on the OLED. We'll use the I2C protocol to connect the OLED display to the Pico.

 ### Hardware Requirements
 
 For this project, you'll need:
 - An OLED display (0.96 Inch I2C/IIC 4-Pin, 128x64 resolution, SSD1306 chip)
 - A breadboard
 - Jumper wires

+## Setup
+We will connect the SDA to GPIO 18 and the SCL to GPIO 19. Attach VCC to 3.3V for power, and GND to GND. This setup allows the OLED display to communicate with the microcontroller using I2C.
