Free, in the browser: try it in the simulator first, then buy only the parts it needs.

What you can build

Lights that follow who passes

Three sensors along the path, the strip lights the stretch where someone is.

Parts: Motion sensor, WS2812 LED strip

The request it sends: «Three motion sensors along a corridor and a 30-pixel LED strip: light in blue the stretch where someone passes and turn it off after»

Misters when it is hot

Over 30 °C the pump mists, under 28 °C it stops.

Parts: BME280 climate sensor, MOSFET driver, 12 V pump

The request it sends: «Turn the misters' pump on over 30 degrees and off under 28»

How it works

  1. Pick a project or describe yours in words, in your language.
  2. The assistant chooses real parts, draws the wires and writes the program; you try it in the simulator.
  3. You put the parts on an ESP32 board as drawn, load the program from the browser, and the board runs on its own.

Need something else?

Write what you need in your own words: the assistant proposes the project and tells you if something cannot be done.
