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
