MQTT PubSubClient Tutorial for Arduino, ESP8266, and ESP32

MQTT Tutorial for Raspberry Pi, Arduino, and ESP8266

Note that the library only works with networking libraries that support the Arduino Client interface. This means the library will work with the Ethernet shield, CC3000 or even ESP8266 Arduino, but not the FONA platform because it does not have a Client interface. Below is a small example that shows using the PubSubClient library with the CC3000.

Temperature Dashboard Using Arduino UNO, ESP8266 And MQTT

/10/2016// NOTE: For working with a faster than ATmega328p 16 MHz Arduino chip, like an ESP8266, // you need to increase the threshold for cycle counts considered a 1 or 0. // You can do this by passing a 3rd parameter for this threshold. It's a bit // of fiddling to find the right value, but in general the faster the CPU the // higher the value.

ESP8266: Connecting to MQTT broker – techtutorialsx

/3/2015You can use the Arduino Uno as a USB to TTL connector allowing you to communicate with the ESP8266. BE ADVISED that the ESP8266 is rated at 3. 3V and the UNO RX and TX pins are rated as 5V but i've had no issues so far.
