Learn electronics with two fun Pi Day projects using the Raspberry Pi Pico! This digital guide includes complete MicroPython source code, step-by-step wiring diagrams, a full pinout reference, and detailed breadboard connection photos from multiple angles.
? Included Experiments:
- Experiment 1: LED Morse Code Pi — Blink the digits of Pi (3.14159...) in Morse code using a green LED. Perfect first project — only 2 components + 1 wire!
- Experiment 2: LCD Scrolling Pi Digits — Display the first 100 digits of Pi scrolling across a 1602 LCD screen with "Happy Pi Day from ProTechTrader.com" scrolling on the bottom line. Splash screen shows "Pi Day 2026! / @ProTechTrader"
? Complete Pico Pinout Reference
Full 40-pin diagram with highlighted connection points:
- ? Pin 40 (VBUS) — RED wire → LCD VCC (5V power)
- ⚫ Pin 38 (GND) — BLACK wire → LCD GND (ground)
- ? Pin 6 (GP4/SDA) — BLUE wire → LCD SDA (data)
- ? Pin 7 (GP5/SCL) — YELLOW wire → LCD SCL (clock)
? 10 Connection Reference Photos
AI-generated reference images from every angle — top-down, 3D perspective, close-ups of pins, LCD backpack detail, and cartoon wiring diagram.
