Build Your Own Mini Project

Recommended before this lesson:

Your objective

Choose one bounded project: Blink (three ON/OFF cycles, 1 second each), Street Light (LED ON below 30%, OFF at/above), or Irrigation Indicator (reservoir ≥20% AND temperature >30°C). Complete its observed rubric; other inventions are practice only.
Read the timestamped trace and exported code. Explain which state changed, how long it lasted, and why the input caused that response. Change your blocks and run again; Stop cancels, Reset keeps your blocks. Explanations are for reflection, not automatically graded.

Translations are draft and need educator review.

Drag blocks from the toolbox into the workspace. Connect statement blocks beneath Start. Use the zoom controls to see your program.

My Projects

Choose a supported example

Run and follow this lesson’s rubric and hints. Completion requires observed behavior in one finished run.

Stop ends the current run and keeps the current device state. Reset clears the device and output, keeping blocks.

Virtual LED

Teaching model: external active-high LED on GPIO 2 (HIGH = ON). Real board wiring differs. This simulation does not verify physical firmware.

Read-only code preview

Connect one Start and all supported blocks with valid values to preview or run.

Editor keyboard and screen reader access has not been verified. The surrounding instructions and controls are keyboard accessible. Practical alternatives: run the preloaded starter program, import/export workspace JSON, or inspect the read-only JavaScript, MicroPython, and C++ code preview.
