Real Power meter with OLED display, no wifi
/*
* This sketch sends ads1115 current sensor data via HTTP POST request to thingspeak server.
* It needs the following libraries to work (besides the esp8266 standard libraries supplied with the IDE):
*
* - https://github.com/adafruit/Adafruit_ADS1X15
* - https://github.com/adafruit/Adafruit-GFX-Library
* - https://github.com/adafruit/Adafruit_SSD1306
*
* designed to run directly on esp8266-12 module, to where it can be uploaded using this marvelous piece of software:
