While the health impacts of environmental air pollution on the general population are well established, its effects on occupational groups remain less understood. Outdoor workers are exposed to higher levels of environmental air pollution due to the nature of their work, especially in the context of frequent wildfire smoke events and global climate change. The … Read more

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
