With this tutorial, we will learn how to handle with this fantastic little device, the NodeMCU ESP-12E Development Kit V. 1.0.
The overall idea will be:
- Blinking a single LED
- Connect the ESP to an OLED display
- Capturing local data from digital and analog sensors
- Upload data to an IoT service as Thinkspeak
- Display and control “things”, using smartphone app’s as BLYNK
