Continuing our series from last week, we’re going to package up the Wemos D1 Mini and the BME280 Environmental sensor on a perfboard, with batteries. Or at least that was the plan until we ran into a software bug… which could have been fixed. Until… well, watch the video and count how many ways this project didn’t go according to plan. If you agree that #LearningIsEducation please leave a like...

This week we’re starting to make our Micropython powered Wemos D1 truly useful with a sensor and data collection. We’ll wire up a BME280 sensor which measures temperature, humidity and air pressure. After we know it works, we’ll use Wifi and MQTT to send the data to a website for viewing. (View on youtube)
Last week we covered how to flash Micropython onto an ESP8266 (Wemos D1 Mini) but we had to type our code into the REPL by hand. That’s not terribly useful for a real world project, so this week we learn how to upload code and make it run on boot. We’ll be using a tool called Ampy, by Adafruit, since the Micropython world is a little immature.
