|I needed a high activity Twitter hash tag. What could be more
active today than #FIFAgate?
My first little project was to pass on a twitter feed through MQTT to a NodeMCU ESP8266 module with an attached OLED display. It was super easy and even more versatile than I expected. I can now shift away the logic from the ESPs which are always short on RAM to the central node running on a Raspberry Pi. The stream can then easily be setup in the browser. As soon as you press “deploy” the changes will become visible on the OLED display.
|The twitter flow: get the tweets from twitter, beautify them a little
throttle the news feed to not overload the ESP and send them to the
ESP over MQTT.
