I just finished a cool project with my new Cactus Micro rev2 (Arduino w/ ESP8266 WiFi built-in) and an OLED screen. My Internet of LEGO project is basically a collection of IoT, computer & electronics ideas brought to life, for my own personal amusement.
Check it out!
I've been working on this Arduino project for a while. Mostly mechanical issues, but finally got a solid solution for my LEGO train track switch. I am also using IoT style messaging to emulate a distributed network of "things". It's a little overkill for a single track switch, but it helps to understand the bigger picture with these types of technologies. I plan on integrating this with a train schedule API so I can send the train down a path based on real-world data. I also have an OLED display in the mail, so will be cool to show train times as well.
This Lego Weather Station is an exercise in IoT concepts using an Arduino (Cactus Micro Rev2) which has a built-in ESP8266 WiFi module. It then sends the sensor data using MQTT to a Mosca MQTT broker. A Node-RED client subscribes to the data feed, stores it into a MongoDB and then visualizes it with a Google Chart. The blog article is more about the journey than just the destination . This is one of many cool projects in the Internet of Lego city, which examines all sorts of interesting embedded, NodeJS and IoT concepts using Lego.
