Re: LCD 1602 - Library

Most Excellent ! Many thanks @dhylands, @mcauser, and @ernitron. :D I've wanted to get these displays working with esp/uP for some time now. I put a level shifter in the mix as it's likely the i2c lines are pulled to 5V on the LCD backpack which might put the ESP at risk. Not sure that is really nee...

esp8266-20161110-v1.8.6.bin

How-to: Using MQTT with Adafruit.IO and Thingspeak

I've been learning how to use MQTT with two free hobbyist cloud data services. The MQTT protocol is supported in a built-in library in the Micropython binaries -- this protocol can be used send data from your ESP8266, over WIFI, to a free cloud database. For example, your ESP board could read an I2C...
