How to Submit Your Lab Every lab submission must include: Session number and lab name (e.g. "Lab 2.1.1 — UART Deep Dive") What it does — one paragraph description Code — paste your firmware using code blocks Evidence — serial output screenshot OR wiring photo OR video link What you learned — one sentence Format example: Lab: 2.1.1 — UART Two-Board Communication Description: Connected two ESP32 boards via UART. Board A sends a SensorReading_t struct every 2 seconds. Board B receives, parses, and prints. // your code here Serial output: [INF][1234] Received: temp=27.4, hum=62.1 What I learned: UART needs shared GND — forgot this and got garbage data for 20 minutes. Tag your post with the block tag e.g. block-2
