Few weeks ago I was playing around with a 1602 LCD module and my ESP8266. I was disappointed by the number of wires that were running between the ESP8266 and the LCD display. It was a mess!
The I2C bus is a very flexible serial bus invented by Philips Semiconductors (Now NXP) that is used to connect ICs to Microcontrollers at low speeds at short distances.

I have been playing around with MicroPython for a while now. I enjoy writing straight up C/C++ code but MicroPython has brought the ease of Python to embedded platforms especially ESP8266. ESP8266 and MicroPython make a killer combo.
I’ve written about the ESP8266 and built a couple projects with it already. I’ve built a WiFi temperature sensor using the ESP8266 board that publishes the temperature over MQTT to a central data logging server. It’s a fun project.
