MQTT controlled servo with ESP8266 and AVR/Arduino

https://twitter.com/hubmartin Small example using espduino software library. This version supports REST API and also MQTT which I demonstrate here. https://github.com/hubmartin/telepresence You need to flash ESP8266 with esp_bridge binary. API calls in your AVR/CPU are converted to the SLIP commands over serial line and it just works perfectly! Just be careful thet you need some voltage level shifter or at lease resistors/voltage dividers. My AVR runs on 5V and ESP needs 3.3V for power supply and comunication signals!!! https://github.com/tuanpmt/espduino https://github.com/tuanpmt/esp_bridge
