IoT data logger with ESP8266 – part 2

This is the second part of the series on IoT data logging with the ESP8266 WiFi module. I’ll discuss connecting it to an Arduino, Hardware and Software Serial, debugging with Serial Monitor, and uploading the data to the cloud. From the previous article, to make my IoT device, I used: Arduino UNO board (or any higher…
