From idea to hardware.
Start from your idea and describe what you want to build: get the right parts, the schematic and the program. Test them in the simulator with the same code that will go on the board, and buy and assemble only when you're sure it works.
Try it without an account, in your browser: nothing to install. To put it on the board you only need Chrome or Edge and a USB cable.

Projects and missions
What you can build.
Every card is a complete project: the program, the parts, every wire.
- ProjectSelf-watering potDry soil: the pump waters it, and never runs dry.
- ProjectRoom air monitorCO2, temperature and humidity on a screen, and a light that says when to open the window.
- ProjectStair night lightIn the dark, walking by lights the strip; it switches itself off.
- ProjectTraffic lightThree LEDs that take turns, like a real one. The first project.
- ProjectThirsty plant alarmDry soil: a red light and a beep until you water it.
- MissionVoice-controlled robotDrives itself, avoids obstacles and obeys "go", "left", "right", "stop".
- MissionAutomatic wateringA relay switches the pump on a schedule: spray, wait, repeat.
- MissionLine follower robotThree sensors steer the wheels to stay on the line.
- ProjectMailbox alertA magnet on the flap: when the post arrives, a yellow light and a sound.
- ProjectPet feederA servo opens the flap for one second every eight hours.
- ProjectGarage door buttonA relay presses your opener's wall button for you.
A Mission is a complete Chip BASIC program: you read it, edit it, tune it with sliders and save it on the board.

How it works
Four steps.
- 1PickStart from a project or say in words what it should do.
- 2TryThe program runs in the simulator with the parts and wires, before you touch hardware.
- 3BuyOnly the parts it needs, real products with their link.
- 4BuildThe same program goes on the board and works on its own.
Boards and technology
One workbench, three boards.
One language and one bytecode for all; each board with its own capabilities.

The people behind Text to Chip
Three minds. One workbench.
Different backgrounds, different obsessions. One shared idea: technology should turn curiosity into something real.
Questions, answered
Four things to know.
- What is Text to Chip?
- A browser-based electronics workbench for building things that run on their own: a watering system, a lamp, an alarm, a robot. Pick a project or describe it in plain words; the workbench lists the real components, draws the wiring, prepares a short readable program in Chip BASIC, tries it in the simulator and runs it on a board over USB. Nothing to install.
- Do I need hardware to start?
- No. The simulator runs the same bytecode as the real board, with LEDs, buttons, sensors, a buzzer, a servo and a robot. When you get a board, the same program runs on it unchanged. The simulator proves the logic; the wiring and the electrical side you check with the assembly guide and on the real board.
- Which boards does it support?
- Three. The ESP32-S3 (a devkit costs around 20 euros) installs from the browser and runs programs, missions and voice commands. The Nordic nRF54LM20 DK adds the camera and AI on its Axon NPU. The Arduino UNO R4 WiFi installs from the browser and runs programs, with no AI or motors yet.
- Which browser do I need, and what do I buy?
- Any modern browser for the workbench and the simulator; a Chromium browser (Chrome, Edge, Brave) on a computer to connect a board, because the board talks over Web Serial. To build for real, every project lists its exact parts: typically the board plus a few euros of components.
