Write, edit and execute Python directly in your browser. No installation required.
Add LEDs, buttons, LCDs, sensors, buzzers, resistors and much more with simple drag & drop.
Save your experiments online and continue learning from any device.
LEDs, RGB LEDs, LCD1602, Seven Segment Display, Buttons, Relays, Buzzers and many more.
Designed for engineering colleges, universities, schools and IoT training institutes.
Windows, Linux, macOS and Chromebook. Only a modern web browser is needed.
Learn embedded programming from anywhere without buying expensive development kits.
CircuitPi combines a modern Python editor with an interactive breadboard so students can instantly visualize how their code controls hardware.
Start with an empty workspace or choose a ready-made template.
Drag LEDs, LCDs, buttons, sensors and electronic components onto the breadboard.
Control GPIO pins using familiar Python syntax.
Execute the code instantly and observe the virtual hardware respond in real time.
No hardware setup. No SD card. No operating system installation. Just open your browser and start building.
