dMeccano: electronics & digital
Taking a short interlude to describe a range of hardware and software IOT projects. We hope that you find them useful. Our intention is to help bring a “meccano” like approach for people interested in exploring an Internet of Things, Digital technologies and Data. our focus will be on approachable and inexpensive projects that inspire some useful adventures.
