A friend recently gave me an ESP12E module to play with. I’ve previously played with the ESP8266 at Open Source Hardware Camp 2015 when Omer Kilic ran an ESP8266 workshop. The workshop focused on NodeMCU and LUA.
My immediate thought there was to use LUA again and I built some NodeMCU firmware to experiment with different LUA scripts. It worked pretty well. Later I wanted to have a go with the NodeMCU support in the Arduino IDE. That turns out to be very nicely done 🙂
I’ve therefore added a couple of DS18B20 digital one-wire temperature sensors to the board and made use of the OneWire, DallasTemperature and Thingspeak libraries in order to collect data and push it to the web.Continue reading
