WeMos D1 mini (esp8266), debug on secondary UART – Part 3
WeMos D1 mini have 2 UART, one on dedicated pins and a transmit-only UART that can be enabled on GPIO2 (D4), It’s very usefully for debug.

Send email with esp8266 and Arduino (Library v1.x)
A simple method to notify a problem is to use email, It’s very usefully and simple to share, so I created a library to do It. I get some code from GSender a library that It’s quite simple, but not so complete and configurable.
WeMos D1 mini (esp8266), integrated SPIFFS Filesystem – Part 2
Serial Peripheral Interface Flash File System, or SPIFFS for short. It’s a light-weight file system for microcontrollers with an SPI flash chip. The on-board flash chip of the ESP8266 has plenty of space for your files.
WeMos D1 mini (esp8266), pinout, specs and IDE configuration – Part 1
WeMos D1 mini, a little guide to use this low cost but powerful microcontroller with WIFI integrated.
Specification and IDE configuration to start use It.

ATtiny Programmer Board (ArduinoUNO As ISP)
I really like the ATtiny and programming it, so I built a simple board to use Arduino UNO as ISP in a faster way.
PCF8575 i2c 16 bit digital I/O expander
Library to use i2c pcf8575 IC with arduino and esp8266.
This IC can control (until 16) digital devices like button or led with 2 only pins.
Can read and write digital value with only 2 wire (perfect for ESP-01).
I try to simplify the use of this IC, with a minimal set of operation.
Temperature humidity sensors comparison (Data) Part 3
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer (competitor bmp280, DHT11, DHT22, Dallas and thermistor).
Finally the comparison.
Temperature humidity sensors comparison (Code configuration) Part 2
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer (competitor bmp280, DHT11, DHT22, Dallas and thermistor).
Today the code to get sensors fully working.
Temperature humidity sensors comparison (Specifications) Part 1
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer, and introduce the competitor bmp280, DHT11, DHT22, Dallas and thermistor.
Today the specification of the sensors I use.
