When LEGO Meets Arduino: Building a PM2.5 Detector with LEGO

Last week’s article discussed how to control LEGO with Arduino through Bricktronics, building a bridge of communication between Arduino and LEGO. Through this communication mechanism, we can integrate Arduino’s rich peripheral detectors into our application system, giving wings to our creativity. When writing last week’s article, it was during a haze period, but the “unruly … Read more
