About

blokdots is a visual tool for building interactive hardware. Connect sensors, motors, and more with a simple trigger-action interface — no coding required. 3.0 is a ground-up rebuild with our own C++ framework — replacing Firmata entirely. Export real C++ or JavaScript code, hand off to engineering, or go fully standalone: upload directly to Arduino, no more laptop needed! Connects to ProtoPie, Figma, and Socket.IO for integrated UI + hardware prototyping.
